# Combos
> Build a market maker integration for pricing and executing Combos
Combos are multi-leg positions that combine multiple underlying market outcomes
into one YES or NO position. Each Combo is defined by its legs and identified by
derived YES and NO position IDs.
The request for quote (RFQ) system enables quote-based Combo execution between
two participants: Polymarket users (requesters) and market makers (quoters). A
user creates a Request, which starts an auction among connected market makers.
Market makers compete by submitting Quotes: executable prices they are willing to
fill.

```
1. **User creates an unsigned Request** for a Combo price.
2. **RFQ system sends the Request** to connected market makers.
3. **Market makers submit signed Quotes** within the 400 ms submission window.
4. **RFQ system returns the best Quote** to the user.
5. **User accepts the Quote** by signing the trade within the 10-second
acceptance window.
6. **RFQ system requests Last Look confirmation** when Last Look is enabled.
7. **Market maker confirms or declines** within the 1-second confirmation window.
8. **RFQ system executes the accepted Combo**.
9. **User receives execution updates**.
10. **Market maker receives execution updates**.
11. **Connected market makers receive confirmed trade broadcasts**.
Combo position IDs are complementary to CLOB token IDs. A user can trade the
market on the CLOB or can include the market as a leg of a Combo.
This guide shows market makers how to handle Combo RFQs. You will open a quoting
session, respond to incoming requests, cancel submitted quotes when needed,
confirm fills through Last Look, and monitor execution updates.
For development updates on market making for Combos, join the [Combos market
maker Telegram group](https://t.me/+eyMtdtKasWZjYTMx).
## Start Quoting
Start by preparing an authenticated quoting session with the RFQ system. You
need a Polymarket account; create one at [polymarket.com](https://polymarket.com).
Install the Unified TypeScript SDK with the package manager of your choice.
```bash pnpm theme={null}
pnpm add @polymarket/client@beta viem
```
```bash npm theme={null}
npm install @polymarket/client@beta viem
```
```bash yarn theme={null}
yarn add @polymarket/client@beta viem
```
This page uses Viem for wallet signing. See the [TypeScript tooling
guide](/dev-tooling/typescript) for other wallet library integrations.
Create an instance of `SecureClient` with a wallet that has funds for fulfilling
user requests and its signer details.
```ts theme={null}
import { createSecureClient, relayerApiKey } from "@polymarket/client";
import { privateKey } from "@polymarket/client/viem";
const client = await createSecureClient({
wallet: process.env.POLYMARKET_WALLET_ADDRESS!,
signer: privateKey(process.env.PRIVATE_KEY!),
apiKey: relayerApiKey({
key: process.env.RELAYER_API_KEY!,
address: process.env.RELAYER_API_KEY_ADDRESS!,
}),
});
```
The Relayer API key is necessary for setting up trading approvals in the next
step. Create a [Relayer API key](https://polymarket.com/settings?tab=api-keys)
from Settings > API Keys.
Set up the approvals required to fill user requests.
```ts theme={null}
await client.setupTradingApprovals();
```
Open the RFQ session.
```ts theme={null}
const session = await client.openRfqSession();
for await (const event of session) {
// event: RfqEvent
}
```
You can close the session at any time by calling `session.close()`.
```ts theme={null}
for await (const event of session) {
if (shouldCloseSession) {
await session.close();
break;
}
// …
}
```
Install the Python SDK with the package manager of your choice.
```bash uv theme={null}
uv add polymarket-client
```
```bash pip theme={null}
pip install polymarket-client
```
```bash poetry theme={null}
poetry add polymarket-client
```
Create an `AsyncSecureClient` with a wallet that has funds for fulfilling user
requests and its signer details.
```python theme={null}
import os
from polymarket import AsyncSecureClient, RelayerApiKey
client = await AsyncSecureClient.create(
private_key=os.environ["PRIVATE_KEY"],
wallet=os.environ["POLYMARKET_WALLET_ADDRESS"],
api_key=RelayerApiKey(
key=os.environ["RELAYER_API_KEY"],
address=os.environ["RELAYER_API_KEY_ADDRESS"],
),
)
```
The Relayer API key is necessary for setting up trading approvals in the next
step. Create a [Relayer API key](https://polymarket.com/settings?tab=api-keys)
from Settings > API Keys.
Set up the approvals required to fill user requests.
```python theme={null}
await client.setup_trading_approvals()
```
Open the RFQ session.
```python theme={null}
async with client.open_rfq_session() as session:
async for event in session:
# event: RfqEvent
...
```
You can close the session at any time by calling `await session.close()`.
```python theme={null}
async with client.open_rfq_session() as session:
async for event in session:
if should_close_session:
await session.close()
break
...
```
Use Polygon mainnet chain ID `137` for CLOB authentication and Exchange v3
order signing.
Connect to the RFQ system WebSocket.
```text theme={null}
wss://combos-rfq-gateway-quoter.polymarket.com/ws/rfq
```
To inspect the stream before integrating:
```bash theme={null}
wscat -c "wss://combos-rfq-gateway-quoter.polymarket.com/ws/rfq"
```
Some write operations are also available through the REST API.
```text theme={null}
https://combos-rfq-api.polymarket.com
```
RFQ WebSocket authentication uses CLOB API credentials: API key, secret, and
passphrase. If you need credentials, start with [Getting API
Credentials](/api-reference/authentication#using-the-rest-api).
Resolve the order signer identity before sending `auth`. The RFQ system needs
the address that signs the order, the wallet that funds the order, and the
signature type that connects those two addresses.
| Wallet Type | `signature_type` | `signer_address` | `maker_address` |
| -------------- | ---------------- | ----------------------------- | -------------------- |
| Deposit Wallet | `3` POLY\_1271 | Deposit wallet address | Deposit wallet |
| Safe Wallet | `2` Safe | Authenticated signing address | Derived Safe wallet |
| Poly Proxy | `1` Proxy | Authenticated signing address | Derived proxy wallet |
| EOA | `0` EOA | EOA address | Same EOA address |
For more detail, see [Signature Types and
Funder](/api-reference/authentication#signature-types-and-funder).
Send `auth` as the first WebSocket message within 30 seconds. Include the CLOB
credentials and the `signer_address`, `maker_address`, and `signature_type`
values resolved in the previous step. This example uses a Deposit Wallet.
```json theme={null}
{
"type": "auth",
"auth": {
"apiKey": "YOUR_API_KEY",
"secret": "YOUR_API_SECRET",
"passphrase": "YOUR_API_PASSPHRASE"
},
"identity": {
"signer_address": "",
"maker_address": "",
"signature_type": 3 //
}
}
```
Authentication returns a success or failure response.
```json Success theme={null}
{
"type": "auth",
"success": true,
"address": "0xAuthenticatedAddress",
"role": "maker"
}
```
```json Failure theme={null}
{
"type": "auth",
"success": false,
"error": "unauthenticated"
}
```
The RFQ system uses WebSocket protocol heartbeat frames to keep the connection
alive. It sends a ping frame every 30 seconds with payload `rfq`; your client
must respond with a pong frame that echoes the same payload. Most WebSocket
clients handle this automatically. These are protocol frames, not JSON
messages in the RFQ event stream. The gateway closes stale connections after 2
minutes without an inbound message or pong.
Before posting quotes, `maker_address` must approve the contracts that may
transfer assets during RFQ execution.
| Approval | Required when | Contract call |
| --------------------------- | --------------------------------------------- | ------------------------------------------------------- |
| pUSD collateral | The quoted order transfers pUSD | `CollateralToken.approve(ExchangeV3, maxUint256)` |
| Combo positions | The quoted order transfers Combo positions | `PositionManager.setApprovalForAll(ExchangeV3, true)` |
| AutoRedeemer Combo operator | You want automatic redemption flows to use it | `PositionManager.setApprovalForAll(AutoRedeemer, true)` |
Use these contract addresses to build the approval calls.
| Contract | Address |
| --------------------- | -------------------------------------------- |
| pUSD collateral token | `0xC011a7E12a19f7B1f670d46F03B03f3342E82DFB` |
| Exchange v3 | `0xe3333700cA9d93003F00f0F71f8515005F6c00Aa` |
| PositionManager | `0x006F54F7f9A22e0000CC2AB60031000000ae9fEF` |
| AutoRedeemer | `0xa1200000d0002264C9a1698e001292D00E1b00af` |
The following steps show the Deposit Wallet
[batch](/trading/deposit-wallets#submit-a-deposit-wallet-batch) path. If you
are trading with an EOA, submit the approvals directly from `maker_address`.
For Safe or Poly Proxy wallet flows, use an SDK.
Encode the approval calls that are not already in place.
```solidity ERC-20 Approval theme={null}
function approve(address spender, uint256 amount) returns (bool);
```
```solidity ERC-1155 Approval theme={null}
function setApprovalForAll(address operator, bool approved);
```
Build a relayer call list from the encoded calldata.
```json theme={null}
[
{
"target": "0xC011a7E12a19f7B1f670d46F03B03f3342E82DFB",
"value": "0",
"data": ""
},
{
"target": "0x006F54F7f9A22e0000CC2AB60031000000ae9fEF",
"value": "0",
"data": ""
},
{
"target": "0x006F54F7f9A22e0000CC2AB60031000000ae9fEF",
"value": "0",
"data": ""
}
]
```
Fetch a fresh `WALLET` nonce before signing the batch.
```bash theme={null}
curl -G "https://relayer-v2.polymarket.com/v1/account/transactions/params" \
-H "RELAYER_API_KEY: $RELAYER_API_KEY" \
-H "RELAYER_API_KEY_ADDRESS: $RELAYER_API_KEY_ADDRESS" \
--data-urlencode "address=$RELAYER_API_KEY_ADDRESS" \
--data-urlencode "type=WALLET"
```
The response includes the nonce to sign with the transaction.
```json theme={null}
{
"address": "",
"nonce": ""
}
```
Build and sign a Deposit Wallet `Batch` with the owner. Use the approval calls
from the call-list step as `calls`.
```json EIP-712 Batch theme={null}
{
"domain": {
"name": "DepositWallet",
"version": "1",
"chainId": 137,
"verifyingContract": ""
},
"types": {
"Call": [
{ "name": "target", "type": "address" },
{ "name": "value", "type": "uint256" },
{ "name": "data", "type": "bytes" }
],
"Batch": [
{ "name": "wallet", "type": "address" },
{ "name": "nonce", "type": "uint256" },
{ "name": "deadline", "type": "uint256" },
{ "name": "calls", "type": "Call[]" }
]
},
"primaryType": "Batch",
"message": {
"wallet": "",
"nonce": "",
"deadline": "",
"calls": [
{
"target": "0xC011a7E12a19f7B1f670d46F03B03f3342E82DFB",
"value": "0",
"data": ""
}
]
}
}
```
Submit the signed batch to the relayer.
```bash theme={null}
curl -X POST "https://relayer-v2.polymarket.com/submit" \
-H "Content-Type: application/json" \
-H "RELAYER_API_KEY: $RELAYER_API_KEY" \
-H "RELAYER_API_KEY_ADDRESS: $RELAYER_API_KEY_ADDRESS" \
-d '{
"type": "WALLET",
"from": "",
"to": "0x00000000000Fb5C9ADea0298D729A0CB3823Cc07",
"nonce": "",
"signature": "",
"metadata": "Approve Combo RFQ contracts",
"depositWalletParams": {
"depositWallet": "",
"deadline": "",
"calls": [
{
"target": "0xC011a7E12a19f7B1f670d46F03B03f3342E82DFB",
"value": "0",
"data": ""
}
]
}
}'
```
The response includes the relayer transaction ID.
```json theme={null}
{
"transactionID": "",
"state": "STATE_NEW"
}
```
Poll the relayer transaction until it reaches `STATE_CONFIRMED` before posting
quotes that rely on those approvals.
```bash theme={null}
curl "https://relayer-v2.polymarket.com/v1/account/transactions/" \
-H "RELAYER_API_KEY: $RELAYER_API_KEY" \
-H "RELAYER_API_KEY_ADDRESS: $RELAYER_API_KEY_ADDRESS"
```
```json theme={null}
{
"transaction_id": "",
"transaction_hash": "",
"state": "STATE_CONFIRMED",
"error_msg": null
}
```
Treat `STATE_FAILED` and `STATE_INVALID` as terminal failures.
## Handle Quote Requests
Quote requests describe a user's intent to buy or sell shares in a Combo defined
by a given set of legs. A quote request can currently only buy or sell the YES
side of a Combo.
The following cases show how a market maker can satisfy a user's buy or sell
request using collateral or inventory.
| Quote Request | Using Collateral | From Inventory |
| ------------- | --------------------- | ---------------------- |
| Buy YES | Buy NO at `1 - price` | Sell YES at `price` |
| Sell YES | Buy YES at `price` | Sell NO at `1 - price` |
See [Combinatorial Positions](/trading/ctf/combinatorial) for more detail on the
YES/NO position model.
The diagram below shows the maker-side quote lifecycle, from receiving a quote
request through its terminal outcome.
```mermaid theme={null}

style lastLook fill:#165DFC14,stroke:#165DFC66,stroke-width:1px
```
### Authorize the Quote
Authorize each quote by pricing the request and returning a signed order to the
RFQ system. Quoters should respond within the **400 ms** submission window.
First, switch on `event.type` to handle quote requests from the session stream.
```ts theme={null}
switch (event.type) {
case "quote_request":
// event: RfqQuoteRequestEvent
void handleQuoteRequest(event);
break;
// …
}
```
Then, inspect the `RfqQuoteRequestEvent` before pricing it.
| Field | Type | Description |
| -------------------- | ---------------------- | ------------------------------------------ |
| `rfqId` | `RfqId` | RFQ identifier used to correlate responses |
| `requestorPublicId` | `RfqRequestorPublicId` | Public identifier for the user request |
| `conditionId` | `ComboConditionId` | Derived Combo condition ID |
| `direction` | `RfqDirection` | Whether the user wants to buy or sell |
| `side` | `RfqSide.Yes` | Currently always `RfqSide.Yes` |
| `requestedSize` | `RfqRequestedSize` | User-requested notional or share size |
| `yesPositionId` | `PositionId` | Derived YES Combo position ID |
| `noPositionId` | `PositionId` | Derived NO Combo position ID |
| `legPositionIds` | `PositionId[]` | Underlying leg position IDs |
| `submissionDeadline` | `EpochMilliseconds` | Unix-millisecond quote submission deadline |
`requestedSize` is an `RfqRequestedSize` value that describes how the user sized
the request.
```ts theme={null}
type RfqRequestedSize =
| {
unit: RfqRequestedSizeUnit.Notional;
value: DecimalString;
}
| {
unit: RfqRequestedSizeUnit.Shares;
value: DecimalString;
};
```
Where:
* `notional`: the target value of the request in collateral currency. For
example, `"3"` means the user wants roughly 3 pUSD worth of the Combo, with the
resulting share size derived from the quote price.
* `shares`: the target number of Combo outcome tokens. For example, `"10"` means
the user wants 10 shares, or 10,000,000 base units.
In both cases, `value` is a normalized decimal string.
Finally, handle pricing, quote submission, and persistence outside the session
loop before the `event.submissionDeadline` deadline. Price the request as pUSD
per YES Combo share; for example, `0.45` means `0.45` pUSD per share. If you do
not want to quote the request, skip submission.
```ts theme={null}
async function handleQuoteRequest(event: RfqQuoteRequestEvent) {
const price = priceComboRequest(event);
if (price === undefined) return;
const reference = await event.quote({ price });
storeQuoteReference(reference);
}
```
First, use `isinstance(...)` to handle quote requests from the session stream.
```python theme={null}
from polymarket import RfqQuoteRequestEvent
async for event in session:
if isinstance(event, RfqQuoteRequestEvent):
await handle_quote_request(event)
```
Then, inspect the `RfqQuoteRequestEvent` before pricing it.
| Field | Type | Description |
| --------------------- | ------------------------ | ------------------------------------------ |
| `rfq_id` | `RfqId` | RFQ identifier used to correlate responses |
| `requestor_public_id` | `RfqRequestorPublicId` | Public identifier for the user request |
| `condition_id` | `ComboConditionId` | Derived Combo condition ID |
| `direction` | `RfqDirection` | Whether the user wants to buy or sell |
| `side` | `RfqSide` | Currently always `RfqSide.YES` |
| `requested_size` | `RfqRequestedSize` | User-requested notional or share size |
| `yes_position_id` | `PositionId` | Derived YES Combo position ID |
| `no_position_id` | `PositionId` | Derived NO Combo position ID |
| `leg_position_ids` | `tuple[PositionId, ...]` | Underlying leg position IDs |
| `submission_deadline` | `int` | Unix-millisecond quote submission deadline |
`requested_size` is an `RfqRequestedSize` value that describes how the user sized
the request.
```python theme={null}
from dataclasses import dataclass
from decimal import Decimal
from polymarket import RfqRequestedSizeUnit
@dataclass(frozen=True, slots=True, kw_only=True)
class RfqRequestedSize:
unit: RfqRequestedSizeUnit
value: Decimal
```
Where:
* `RfqRequestedSizeUnit.NOTIONAL`: the target value of the request in collateral
currency. For example, `Decimal("3")` means the user wants roughly 3 pUSD worth
of the Combo, with the resulting share size derived from the quote price.
* `RfqRequestedSizeUnit.SHARES`: the target number of Combo outcome tokens. For
example, `Decimal("10")` means the user wants 10 shares, or 10,000,000 base
units.
In both cases, `value` is a `Decimal`.
Finally, handle pricing, quote submission, and persistence outside the session
loop before the `event.submission_deadline` deadline. Price the request as pUSD
per YES Combo share; for example, `Decimal("0.45")` means `0.45` pUSD per share.
If you do not want to quote the request, skip submission.
```python theme={null}
from decimal import Decimal
from polymarket import RfqQuoteRequestEvent
async def handle_quote_request(event: RfqQuoteRequestEvent) -> None:
price = price_combo_request(event)
if price is None:
return
reference = await event.quote(price=price)
store_quote_reference(reference)
```
The RFQ system sends `RFQ_REQUEST` messages over the authenticated WebSocket.
Inspect the request before pricing it.
```json Notional Request theme={null}
{
"type": "RFQ_REQUEST",
"rfq_id": "",
"requestor_public_id": "",
"leg_position_ids": ["", ""],
"condition_id": "",
"yes_position_id": "",
"no_position_id": "",
"direction": "SELL",
"side": "YES",
"requested_size": {
"unit": "notional",
"value_e6": "1000000"
},
"submission_deadline": ""
}
```
```json Shares Request theme={null}
{
"type": "RFQ_REQUEST",
"rfq_id": "",
"requestor_public_id": "",
"leg_position_ids": ["", ""],
"condition_id": "",
"yes_position_id": "",
"no_position_id": "",
"direction": "SELL",
"side": "YES",
"requested_size": {
"unit": "shares",
"value_e6": "1000000"
},
"submission_deadline": ""
}
```
A `notional` request specifies a target pUSD amount; the fillable share size is
derived from the quote price. A `shares` request specifies the exact number of
Combo outcome tokens requested.
Decide the `price` in base units for a full share. A full share is `1000000`
share base units, and `1` pUSD is `1000000` pUSD base units. For example, a
price of `0.45` pUSD per share means `price = 450000`.
Determine `size` from the request:
| `requested_size.unit` | `size` |
| --------------------- | -------------------------------------------------- |
| `notional` | `floor(requested_size.value_e6 * 1000000 / price)` |
| `shares` | `requested_size.value_e6` |
Then determine the order token and amounts:
| Quote Request | Token | `makerAmount` | `takerAmount` |
| ------------- | ----------------- | ------------------------------------------ | ------------- |
| `SELL` YES | `yes_position_id` | `ceil(price * size / 1000000)` | `size` |
| `BUY` YES | `no_position_id` | `ceil((1000000 - price) * size / 1000000)` | `size` |
The examples below quote `1` share, so `size = 1000000`.
```json SELL Request theme={null}

}
```
Build the EIP-712 typed-data payload for your wallet type:
* Use `depositWalletTypedData` when `signature_type` is `3`.
* Use `exchangeV3OrderTypedData` when `signature_type` is `0`, `1`, or `2`.

Both payloads use the Exchange v3 EIP-712 domain. `exchangeV3OrderTypedData` is
the direct Exchange v3 `Order` payload. `depositWalletTypedData` is a
`TypedDataSign` wrapper whose `contents` field is the Exchange v3 order and
whose message includes the Deposit Wallet validation fields.
Sign the typed-data payload for the wallet type you authenticated with. The
normal Exchange v3 payload and the Deposit Wallet payload are different:
| Wallet Type | `signatureType` | Payload to sign | `signed_order.signature` |
| -------------- | --------------- | -------------------------- | ------------------------------ |
| Deposit Wallet | `3` | `depositWalletTypedData` | ERC-7739-wrapped signature |
| Safe Wallet | `2` | `exchangeV3OrderTypedData` | Standard 65-byte EVM signature |
| Poly Proxy | `1` | `exchangeV3OrderTypedData` | Standard 65-byte EVM signature |
| EOA | `0` | `exchangeV3OrderTypedData` | Standard 65-byte EVM signature |
The example below shows how to produce `signature` with Viem for both signing
paths.

REST submissions require a client-generated `quote_id`. Use an opaque unique
value; the RFQ system uses the `quote_` prefix followed by 32 lowercase hex
characters.
After submitting a quote, store the RFQ ID and quote ID together. WebSocket
submissions receive both values in the acknowledgement. REST submissions return
the current RFQ snapshot, so use the client-generated `quote_id` from the request.
```json WebSocket theme={null}
{
"type": "ACK_RFQ_QUOTE",
"rfq_id": "",
"quote_id": ""
}
```
```json REST theme={null}
{
"request": {
"rfq_id": ""
// …
},
"status": "COLLECTING_QUOTES",
"competition_started_at": 1780963200000,
"competition_ends_at": 1780963200400
}
```
This reference identifies the submitted quote.
### Quote Partial Fills
If you only want to fill part of the requested size, pass `size` with the quote.
`size` is a normalized decimal value: `"10"` means 10 shares, or 10,000,000 base
units. When omitted, the SDK quotes the full requested size.
```ts theme={null}
await event.quote({
price: "0.45",
size: "10",
});
```
If you only want to fill part of the requested size, pass `size` with the quote.
`size` is a `Decimal`-compatible value: `Decimal("10")` means 10 shares, or
10,000,000 base units. When omitted, the SDK quotes the full requested size.
```python theme={null}
from decimal import Decimal
await event.quote(
price=Decimal("0.45"),
size=Decimal("10"),
)
```
Partial fills use the same signed-order flow as a full quote.
Start by converting `requested_size` into the full request size in share base
units.
| `requested_size.unit` | Full request size |
| --------------------- | -------------------------------------------------- |
| `notional` | `floor(requested_size.value_e6 * 1000000 / price)` |
| `shares` | `requested_size.value_e6` |
Choose a partial `size` in share base units that is smaller than the full request
size.
Compute the signed order amounts from the partial `size`.
| Quote Request | Token | `makerAmount` | `takerAmount` |
| ------------- | ----------------- | ------------------------------------------ | ------------- |
| `SELL` YES | `yes_position_id` | `ceil(price * size / 1000000)` | `size` |
| `BUY` YES | `no_position_id` | `ceil((1000000 - price) * size / 1000000)` | `size` |
This example quotes half of a `1` share request at `0.45` pUSD per share, so
`size = 500000`:
```json SELL Request theme={null}
{
"salt": "",
"maker": "",
"signer": "",
"tokenId": "",
"makerAmount": "225000",
"takerAmount": "500000",
"side": 0,
"signatureType": 3, //
"timestamp": "",

"builder": "0x0000000000000000000000000000000000000000000000000000000000000000"
}
```
```json BUY Request theme={null}
{
"salt": "",
"maker": "",
"signer": "",
"tokenId": "",
"makerAmount": "275000",
"takerAmount": "500000",
"side": 0,
"signatureType": 3, //
"timestamp": "",
"metadata": "0x0000000000000000000000000000000000000000000000000000000000000000",

}
```
Sign the partial order, then submit the quote.
```json theme={null}

"builder": "0x0000000000000000000000000000000000000000000000000000000000000000",
"signature": ""
}
}
```
### Use Inventory
By default, quotes use collateral (pUSD) to buy YES or NO tokens as needed to
satisfy the quote request according to the combinatorial position logic. Pass
`source: "inventory"` when you want to quote from existing inventory instead.
```ts theme={null}
await event.quote({
price: "0.45",
source: "inventory",
});
```
By default, quotes use collateral (pUSD) to buy YES or NO tokens as needed to
satisfy the quote request according to the combinatorial position logic. Pass
`source=RfqQuoteSource.INVENTORY` when you want to quote from existing inventory
instead.
```python theme={null}
from decimal import Decimal
from polymarket import RfqQuoteSource
await event.quote(
price=Decimal("0.45"),
source=RfqQuoteSource.INVENTORY,
)
```
Inventory quotes sell existing outcome tokens instead of spending collateral. The
RFQ quote price still means pUSD per YES Combo share.
Use the token you already hold for the side of the quote request.
| Quote Request | Inventory Token | Order Side |
| ------------- | ----------------- | ---------- |
| `BUY` YES | `yes_position_id` | SELL |
| `SELL` YES | `no_position_id` | SELL |
Compute the signed order amounts from the inventory `size`.
| Quote Request | Order Price | `makerAmount` | `takerAmount` |
| ------------- | ----------------- | ------------- | ------------------------------------------- |
| `BUY` YES | `price` | `size` | `floor(price * size / 1000000)` |
| `SELL` YES | `1000000 - price` | `size` | `floor((1000000 - price) * size / 1000000)` |
This example quotes `1` share at `0.45` pUSD per share, so `price = 450000` and
`size = 1000000`:
```json BUY Request theme={null}
{
"salt": "",
"maker": "",
"signer": "",
"tokenId": "",
"makerAmount": "1000000",
"takerAmount": "450000",
"side": 1,
"signatureType": 3, //
"timestamp": "",
"metadata": "0x0000000000000000000000000000000000000000000000000000000000000000",
"builder": "0x0000000000000000000000000000000000000000000000000000000000000000"
}
```
```json SELL Request theme={null}
{
"salt": "",
"maker": "",
"signer": "",
"tokenId": "",
"makerAmount": "1000000",
"takerAmount": "550000",
"side": 1,
"signatureType": 3, //
"timestamp": "",
"metadata": "0x0000000000000000000000000000000000000000000000000000000000000000",
"builder": "0x0000000000000000000000000000000000000000000000000000000000000000"
}
```
Sign the inventory order, then submit the quote.
```json theme={null}
{
"type": "RFQ_QUOTE",
"rfq_id": "",
"price_e6": "450000",
"size_e6": "1000000",

"salt": "",
"maker": "",
"signer": "",

"makerAmount": "1000000",
"takerAmount": "450000",
"side": 1,
"signatureType": 3, //
"timestamp": "",
"metadata": "0x0000000000000000000000000000000000000000000000000000000000000000",
"builder": "0x0000000000000000000000000000000000000000000000000000000000000000",
"signature": ""
}
}
```
### Cancel Quotes
After you submit a quote, keep the returned quote reference. If your price,
inventory, or risk changes before the quote is selected, use that reference to
request cancellation.
A cancellation acknowledgement means the RFQ system processed the cancellation
request. It does not guarantee the quote was withdrawn from an RFQ that was
already selected.
First, keep the quote reference returned by `event.quote(…)`. It contains the
`rfqId` and `quoteId` needed to cancel the quote.
```ts theme={null}
const reference = await event.quote({ price: 0.45 });
// reference.rfqId: RfqId
// reference.quoteId: RfqQuoteId
```
Then, pass that reference to `session.cancelQuote(…)` on the same live RFQ
session.
```ts theme={null}
if (shouldCancelQuote) {
const ack = await session.cancelQuote(reference);
// ack.rfqId: RfqId
// ack.quoteId: RfqQuoteId
}
```
First, keep the quote reference returned by `event.quote(...)`. It contains the
`rfq_id` and `quote_id` needed to cancel the quote.
```python theme={null}
from decimal import Decimal
reference = await event.quote(price=Decimal("0.45"))
# reference.rfq_id: RfqId
# reference.quote_id: RfqQuoteId
```
Then, pass that reference to `session.cancel_quote(...)` on the same live RFQ
session.
```python theme={null}
if should_cancel_quote:
ack = await session.cancel_quote(reference)
# ack.rfq_id: RfqId
# ack.quote_id: RfqQuoteId
```
Send a cancellation request with the RFQ ID and quote ID. On the WebSocket, the
RFQ system acknowledges a processed cancellation request with
`ACK_RFQ_QUOTE_CANCEL`.
```json Send theme={null}
{
"type": "RFQ_QUOTE_CANCEL",
"rfq_id": "",
"quote_id": "",
"signer_address": "",
"maker_address": ""
}
```
```json Receive theme={null}
{
"type": "ACK_RFQ_QUOTE_CANCEL",
"rfq_id": "",
"quote_id": ""
}
```
Alternatively, cancel the quote through the REST API.
```bash Request theme={null}
curl -X POST "https://combos-rfq-api.polymarket.com/v1/maker/quotes/cancel" \
-H "Content-Type: application/json" \
-H "POLY_ADDRESS: " \

-H "POLY_TIMESTAMP: " \
-H "POLY_API_KEY: " \
-H "POLY_PASSPHRASE: " \
-d '{
"rfq_id": "",
"quote_id": "",
"signer_address": "",
"maker_address": "",
"signature_type": 3
}'
```
```json Response theme={null}
{
"request": {
"rfq_id": ""
// …
},
"status": "COLLECTING_QUOTES",
"competition_started_at": 1780963200000,
"competition_ends_at": 1780963200400
}
```
### Last Look
Last Look is a separate final review step for makers that have it enabled. If a
selected quote requires Last Look, run a final risk check before the deadline and
accept or reject the fill.
Last Look is offered to makers with approximately \$2,500 in Combo notional
volume and an established line of communication with Polymarket. This keeps the
program reliable and helps Polymarket resolve system issues quickly.
To request access, complete the [Last Look request
form](https://forms.gle/dk5A1DRw8EN5uP9z5).
Makers are expected to accept most selected quotes. We track acceptance rates,
and makers who reject more than 15% of selected quotes over a one-hour lookback
window may be paused from quoting for a few minutes.
Once access is enabled, your quoting system will immediately be asked to review
selected fills. Make sure it is ready to evaluate and answer them before approval
is activated.
First, switch on `event.type` to handle confirmation requests from the same
session stream.
```ts theme={null}
switch (event.type) {
case "confirmation_request":
// event: RfqConfirmationRequestEvent
void handleConfirmationRequest(event);
break;
// …
}
```
Then, inspect the confirmation request before running your final risk check. It
includes the selected quote, the final fill size, and the `event.confirmBy`
deadline for your Last Look response.
```ts theme={null}
type RfqConfirmationRequestEvent = {
type: "confirmation_request";
rfqId: RfqId;
quoteId: RfqQuoteId;
conditionId: ComboConditionId;
direction: RfqDirection;
side: RfqSide.Yes;
price: DecimalString;
fillSize: DecimalString;
yesPositionId: PositionId;
noPositionId: PositionId;
legPositionIds: PositionId[];
confirmBy: EpochMilliseconds;
confirm(): Promise;
decline(): Promise;
};
```
Finally, run your final risk check outside the session loop and respond before
the `event.confirmBy` deadline.
```ts theme={null}
async function handleConfirmationRequest(event: RfqConfirmationRequestEvent) {
const canStillFill = runFinalRiskCheck(event);
if (canStillFill) {
await event.confirm();
return;
}
await event.decline();
}
```
First, use `isinstance(...)` to handle confirmation requests from the same
session stream.
```python theme={null}
from polymarket import RfqConfirmationRequestEvent
async for event in session:
if isinstance(event, RfqConfirmationRequestEvent):
await handle_confirmation_request(event)
```
Then, inspect the confirmation request before running your final risk check. It
includes the selected quote, the final fill size, and the `event.confirm_by`
deadline for your Last Look response.
```python theme={null}
class RfqConfirmationRequestEvent:
type: "confirmation_request"
rfq_id: RfqId
quote_id: RfqQuoteId
signer_address: EvmAddress
maker_address: EvmAddress
signature_type: int
condition_id: ComboConditionId
direction: RfqDirection
side: RfqSide
price: Decimal
fill_size: Decimal
yes_position_id: PositionId
no_position_id: PositionId
leg_position_ids: tuple[PositionId, ...]
confirm_by: int
async def confirm(self) -> RfqConfirmationAck: ...
async def decline(self) -> RfqConfirmationAck: ...
```
Finally, run your final risk check outside the session loop and respond before
the `event.confirm_by` deadline.
```python theme={null}
from polymarket import RfqConfirmationRequestEvent
async def handle_confirmation_request(
event: RfqConfirmationRequestEvent,
) -> None:
can_still_fill = run_final_risk_check(event)
if can_still_fill:
await event.confirm()
return
await event.decline()
```
If Last Look is enabled for your maker, the RFQ WebSocket sends
`RFQ_CONFIRMATION_REQUEST` after your quote is selected.
```json theme={null}
{
"type": "RFQ_CONFIRMATION_REQUEST",
"rfq_id": "",
"quote_id": "",
"signer_address": "",
"maker_address": "",
"signature_type": 3, //
"leg_position_ids": ["", ""],
"condition_id": "",
"yes_position_id": "",
"no_position_id": "",
"direction": "BUY",
"side": "YES",
"fill_size_e6": "1000000",
"price_e6": "450000",
"confirm_by": 1780963200000
}
```
Respond before `confirm_by` with `CONFIRM` or `DECLINE`.
```json Confirm theme={null}
{
"type": "RFQ_CONFIRMATION_RESPONSE",
"rfq_id": "",
"quote_id": "",
"decision": "CONFIRM"
}
```
```json Decline theme={null}
{
"type": "RFQ_CONFIRMATION_RESPONSE",
"rfq_id": "",
"quote_id": "",
"decision": "DECLINE"
}
```
The RFQ system acknowledges the response with
`ACK_RFQ_CONFIRMATION_RESPONSE`.
```json theme={null}
{
"type": "ACK_RFQ_CONFIRMATION_RESPONSE",
"rfq_id": "",
"quote_id": "",
"decision": "CONFIRM"
}
```
Do not include `signer_address`, `maker_address`, or `signature_type` in
`RFQ_CONFIRMATION_RESPONSE`. The RFQ system applies identity from the
authenticated session.
Alternatively, send the Last Look decision through the REST API. The response
returns `execution` when your confirmation completes the bundle. If the RFQ is
still waiting on another maker confirmation, or if you decline, it returns
`snapshot`.
```bash Request theme={null}
curl -X POST "https://combos-rfq-api.polymarket.com/v1/maker/confirmations" \

```
```json Execution Response theme={null}

## Manage Combo Positions
Use Combo position workflows to manage inventory throughout the quote lifecycle.
### List Combo Positions
List Combo positions as part of your background inventory sync. Keep this state
fresh outside the quote path.
Use `client.listComboPositions(...)` to page through Combo positions for the
authenticated account. Filter by status, Combo condition ID, or Combo position
ID when you only need a subset of positions.
```ts theme={null}
import { ComboPositionStatus, type ComboPosition } from "@polymarket/client";
const positions = client.listComboPositions({
status: ComboPositionStatus.Open,
pageSize: 50,
});
for await (const page of positions) {
for (const position of page.items) {
// position: ComboPosition
}
}
```
Each returned item is a `ComboPosition`.
```ts ComboPosition theme={null}
type ComboPosition = {
conditionId: ComboConditionId;
positionId: PositionId;
moduleId: number;
userAddress: Address;
shares: DecimalString;
entryAvgPriceUsdc?: DecimalString | null;
entryCostUsdc?: DecimalString | null;
status: ComboPositionStatus;
firstEntryAt: IsoDateTimeString;
resolvedAt?: IsoDateTimeString | null;
legsTotal: number;
legsResolved: number;
legsPending: number;
legs: ComboPositionLeg[];
};
```
```ts ComboPositionLeg theme={null}
type ComboPositionLeg = {
legIndex: number;
legPositionId: PositionId;
legConditionId: CtfConditionId;
legOutcomeIndex: number;
legOutcomeLabel?: string | null;
legStatus: ComboPositionStatus;
legResolvedAt?: IsoDateTimeString | null;
legCurrentPrice?: DecimalString | null;
market?: ComboPositionMarket | null;
};
```
```ts ComboPositionMarket theme={null}
type ComboPositionMarket = {
marketId?: string | null;
slug?: string | null;
title?: string | null;
outcome?: string | null;
imageUrl?: string | null;
iconUrl?: string | null;
category?: string | null;
subcategory?: string | null;
tags?: string[] | null;
endDate?: IsoDateTimeString | null;
event?: ComboPositionMarketEvent | null;
};
```
```ts ComboPositionMarketEvent theme={null}
type ComboPositionMarketEvent = {
eventId?: string | null;
eventSlug?: string | null;
eventTitle?: string | null;
eventImage?: string | null;
};
```
You can filter positions by the following criteria:
```ts Condition ID theme={null}
const positions = client.listComboPositions({
conditionId: "",
});
```
```ts Position ID theme={null}
const positions = client.listComboPositions({
positionId: "",
});
```
```ts Status theme={null}
const positions = client.listComboPositions({
status: ComboPositionStatus.Open,
});
```
Use `client.list_combo_positions(...)` to page through Combo positions for the
authenticated wallet. The Python SDK returns snake\_case model fields and
`Decimal` values for numeric position amounts.
```python theme={null}
positions = client.list_combo_positions(status="OPEN")
async for page in positions:
for position in page.items:
# position: ComboPosition
...
```
The returned `ComboPosition` models include the following fields:
```python ComboPosition theme={null}
class ComboPosition:
condition_id: ComboConditionId
position_id: PositionId
module_id: int
user_address: EvmAddress
shares: Decimal
entry_avg_price_usdc: Decimal | None
entry_cost_usdc: Decimal | None
status: ComboPositionStatus
first_entry_at: datetime
resolved_at: datetime | None
legs_total: int
legs_resolved: int
legs_pending: int
legs: tuple[ComboPositionLeg, ...]
```
```python ComboPositionLeg theme={null}
class ComboPositionLeg:
leg_index: int
leg_position_id: PositionId
leg_condition_id: CtfConditionId
leg_outcome_index: int
leg_outcome_label: str | None
leg_status: ComboPositionStatus
leg_resolved_at: datetime | None
leg_current_price: Decimal | None
market: ComboPositionMarket | None
```
```python ComboPositionMarket theme={null}
class ComboPositionMarket:
market_id: str | None
slug: str | None
title: str | None
outcome: str | None
image_url: str | None
icon_url: str | None
category: str | None
subcategory: str | None
tags: tuple[str, ...] | None
end_date: datetime | None
event: ComboPositionMarketEvent | None
```
```python ComboPositionMarketEvent theme={null}
class ComboPositionMarketEvent:
event_id: str | None
event_slug: str | None
event_title: str | None
event_image: str | None
```
You can filter positions by the following criteria:
```python Condition ID theme={null}
positions = client.list_combo_positions(
condition_id="",
)
```
```python Position ID theme={null}
positions = client.list_combo_positions(
position_id="",
)
```
```python Status theme={null}
positions = client.list_combo_positions(
status="OPEN",
)
```
Use the Data API to list Combo positions for a wallet.
```bash theme={null}
curl -G "https://data-api.polymarket.com/v1/positions/combos" \
--data-urlencode "user=" \
--data-urlencode "limit=50" \
--data-urlencode "status=OPEN"
```
You can filter positions by the following query parameters:
```bash Condition ID theme={null}
curl -G "https://data-api.polymarket.com/v1/positions/combos" \
--data-urlencode "user=" \
--data-urlencode "combo_condition_id="
```
```bash Position ID theme={null}
curl -G "https://data-api.polymarket.com/v1/positions/combos" \
--data-urlencode "user=" \
--data-urlencode "combo_position_id="
```
```bash Status theme={null}
curl -G "https://data-api.polymarket.com/v1/positions/combos" \
--data-urlencode "user=" \
--data-urlencode "status=OPEN"
```
The response returns Combo positions in `combos` and pagination metadata in
`pagination`.
```json theme={null}
{
"combos": [
{
"combo_condition_id": "",
"combo_position_id": "",
"module_id": 3,
"user_address": "",
"shares_balance": "10",

}
```
**Displaying closed (redeemed) positions.** `entry_cost_usdc` is the
*remaining* cost basis (`entry_avg_price × shares_balance`), so it reads `~0`
once a winning combo is redeemed — and `shares_balance` does too. Two fields
carry the closed-position economics instead:
* `realized_payout_usdc` — gross redemption proceeds (winning shares redeem
1:1 at \$1; accumulates under `PARTIAL`)
* `total_cost_usdc` — original cost basis, reconstructed as
`entry_avg_price × (shares_balance + realized_payout)`
Net result of a finished combo = `realized_payout_usdc − total_cost_usdc`.
### Inventory Management
If you want to quote from inventory, build the inventory before quote requests
arrive. Splitting converts collateral into complementary Combo positions for a
set of legs. Merging converts matching complementary Combo positions back into
collateral.
Use `client.splitPosition(...)` with `legs` to create Combo inventory from
collateral. `amount` is in pUSD base units.
```ts theme={null}
const split = await client.splitPosition({
amount: 10_000_000n,
legs: ["", ""],
});
const splitOutcome = await split.wait();
// splitOutcome.transactionHash identifies the confirmed split transaction.
```
Use `client.mergePositions(...)` with the same `legs` to merge complementary
Combo positions back into collateral. Pass `amount: "max"` to merge the largest
matching amount available.
```ts theme={null}
const merge = await client.mergePositions({
amount: "max",
legs: ["", ""],
});
const mergeOutcome = await merge.wait();
// mergeOutcome.transactionHash identifies the confirmed merge transaction.
```
Use `client.split_position(...)` with `legs` to create Combo inventory from
collateral. `amount` is in pUSD base units.
```python theme={null}
split = await client.split_position(
amount=10_000_000,
legs=["", ""],
)
split_outcome = await split.wait()
# split_outcome.transaction_hash identifies the confirmed split transaction.
```
Use `client.merge_positions(...)` with the same `legs` to merge complementary
Combo positions back into collateral. Pass `amount="max"` to merge the largest
matching amount available.
```python theme={null}
merge = await client.merge_positions(
amount="max",
legs=["", ""],
)
merge_outcome = await merge.wait()
# merge_outcome.transaction_hash identifies the confirmed merge transaction.
```
Use the Relayer API to split or merge Combo inventory by sending an ordered list
of encoded contract calls in one batch. The following steps assume you are using
a Deposit Wallet.
If you use a Safe or Poly Proxy wallet, use one of the SDKs instead because
those wallet integrations require wallet-specific signing and encoding.
Use these contract addresses when building the call list.
| Contract | Address |
| --------------------- | -------------------------------------------- |
| CombinatorialModule | `0x30000034706c7d8e12009dab006be20000c031a8` |
| Router | `0x12121212006e4CD160D18e3f00711DA5c3372600` |
| PositionManager | `0x006F54F7f9A22e0000CC2AB60031000000ae9fEF` |
| pUSD collateral token | `0xC011a7E12a19f7B1f670d46F03B03f3342E82DFB` |
First, determine whether the inventory action needs an approval. If approval is
already in place, skip this step.
For a split, `` must approve pUSD spending by the Router. For a
merge, `` must approve the Router as a PositionManager ERC-1155
operator.
```solidity ERC-20 Approval theme={null}
function approve(address spender, uint256 amount) returns (bool);
```
```solidity ERC-1155 Approval theme={null}
function setApprovalForAll(address operator, bool approved);
```
Encode one of these approval calls when needed. Keep the resulting call object;
it will be added before the Combo calls in the next step.
```json Split Approval Call theme={null}
[
{
"target": "0xC011a7E12a19f7B1f670d46F03B03f3342E82DFB",
"value": "0",
"data": ""
}
]
```
```json Merge Approval Call theme={null}
[
{
"target": "0x006F54F7f9A22e0000CC2AB60031000000ae9fEF",
"value": "0",
"data": ""
}
]
```
Then, add the Combo call objects to the ordered list.
For a split, include `prepareCondition` before `split`. `prepareCondition` is
idempotent, so it is safe to include even when the Combo condition was already
prepared. For a merge, call `merge` directly with the Combo condition ID for the
positions being merged.
```solidity theme={null}
function prepareCondition(uint256[] legs) returns (bytes31);
function split(bytes31 conditionId, uint256 amount);
function merge(bytes31 conditionId, uint256 amount);
```
Append these encoded calls after the approval call from the previous step, if one
was needed.
```json Split Combo Calls theme={null}
[
// Include the approval call first when needed.
// …
{
"target": "0x30000034706c7d8e12009dab006be20000c031a8",
"value": "0",
"data": ""
},
{
"target": "0x12121212006e4CD160D18e3f00711DA5c3372600",
"value": "0",
"data": ""
}
]
```
```json Merge Combo Calls theme={null}
[
// Include the approval call first when needed.
// …
{
"target": "0x12121212006e4CD160D18e3f00711DA5c3372600",
"value": "0",
"data": ""
}
]
```
Fetch a fresh `WALLET` nonce before each submission.
```bash theme={null}
curl -G "https://relayer-v2.polymarket.com/v1/account/transactions/params" \
-H "RELAYER_API_KEY: $RELAYER_API_KEY" \
-H "RELAYER_API_KEY_ADDRESS: $RELAYER_API_KEY_ADDRESS" \
--data-urlencode "address=$RELAYER_API_KEY_ADDRESS" \
--data-urlencode "type=WALLET"
```
The response includes the nonce to sign with the transaction.
```json theme={null}
{
"address": "",
"nonce": ""
}
```
Build the Deposit Wallet EIP-712 `Batch` typed data.
```json theme={null}
{
"domain": {
"name": "DepositWallet",
"version": "1",
"chainId": 137,
"verifyingContract": ""
},
"types": {
"Call": [
{ "name": "target", "type": "address" },
{ "name": "value", "type": "uint256" },
{ "name": "data", "type": "bytes" }
],
"Batch": [
{ "name": "wallet", "type": "address" },
{ "name": "nonce", "type": "uint256" },
{ "name": "deadline", "type": "uint256" },
{ "name": "calls", "type": "Call[]" }
]
},
"primaryType": "Batch",
"message": {
"wallet": "",
"nonce": "",
"deadline": "",
"calls": [
// Use the final calls array from the previous steps.
// …
]
}
}
```
Sign the EIP-712 batch with your signer. Use the resulting signature as
`signature` in the relayer submission.
Submit the signed transaction to the Relayer API.
```bash Split theme={null}
curl -X POST "https://relayer-v2.polymarket.com/submit" \
-H "Content-Type: application/json" \
-H "RELAYER_API_KEY: $RELAYER_API_KEY" \

}
}'
```
```bash Merge theme={null}

"depositWalletParams": {
"depositWallet": "",
"deadline": "",
"calls": [
// Use the final calls array from the previous steps.
// …
]
}
}'
```
The response includes the relayer transaction ID.
```json theme={null}
{
"transactionID": "",
"state": "STATE_NEW"
}
```
Poll the relayer transaction until it reaches `STATE_CONFIRMED` before relying on
the updated inventory.
```bash theme={null}
curl "https://relayer-v2.polymarket.com/v1/account/transactions/" \
-H "RELAYER_API_KEY: $RELAYER_API_KEY" \
-H "RELAYER_API_KEY_ADDRESS: $RELAYER_API_KEY_ADDRESS"
```
```json theme={null}
{
"transaction_id": "",
"transaction_hash": "",
"state": "STATE_CONFIRMED",
"error_msg": null
}
```
Treat `STATE_FAILED` and `STATE_INVALID` as terminal failures.
### Redeem Resolved Positions
When a Combo position resolves, redeem the winning position to settle it back to
collateral.
Use `client.redeemPositions(...)` with a Combo `positionId`. The SDK redeems the
available balance for that resolved position.
```ts theme={null}
const redeem = await client.redeemPositions({
positionId: "",
});
const redeemOutcome = await redeem.wait();
// redeemOutcome.transactionHash identifies the confirmed redemption transaction.
```
You can list resolved winning positions first, then redeem each one.
```ts theme={null}
import { ComboPositionStatus } from "@polymarket/client";
for await (const page of client.listComboPositions({
status: ComboPositionStatus.ResolvedWin,
})) {
for (const position of page.items) {
const redeem = await client.redeemPositions({
positionId: position.positionId,
});
await redeem.wait();
}
}
```
Use `client.redeem_positions(...)` with a Combo `position_id`. The SDK redeems
the available balance for that resolved position.
```python theme={null}
redeem = await client.redeem_positions(
position_id="",
)
redeem_outcome = await redeem.wait()
# redeem_outcome.transaction_hash identifies the confirmed redemption transaction.
```
You can list resolved winning positions first, then redeem each one.
```python theme={null}
positions = client.list_combo_positions(status="RESOLVED_WIN")
async for position in positions.iter_items():
redeem = await client.redeem_positions(
position_id=position.position_id,
)
await redeem.wait()
```
Use the Relayer API to redeem resolved Combo positions by sending an ordered list
of encoded contract calls in one batch. The following steps assume you are using
a Deposit Wallet.
If you use a Safe or Poly Proxy wallet, use one of the SDKs instead because
those wallet integrations require wallet-specific signing and encoding.
| Contract | Address |
| --------------- | -------------------------------------------- |
| Router | `0x12121212006e4CD160D18e3f00711DA5c3372600` |
| PositionManager | `0x006F54F7f9A22e0000CC2AB60031000000ae9fEF` |
First, determine whether `` has approved the Router as a
PositionManager ERC-1155 operator. If approval is already in place, skip this
step.
```solidity theme={null}
function setApprovalForAll(address operator, bool approved);
```
Encode the approval call when needed. The approval call becomes the first object
in the final `calls` array.
```json theme={null}
[
{
"target": "0x006F54F7f9A22e0000CC2AB60031000000ae9fEF",
"value": "0",
"data": ""
}
]
```
Set the Router inputs for the redemption.
| Value | Source |
| -------------- | ------------------------------------- |
| `conditionId` | `` |
| `outcomeIndex` | `0` for YES, `1` for NO |
| `amount` | Shares to redeem, in share base units |
The Router accepts `conditionId`, `outcomeIndex`, and `amount`, not `positionId`.
The Router redeem function is:
```solidity theme={null}
function redeem(bytes31 conditionId, uint256 outcomeIndex, uint256 amount);
```
Append the redeem call after the approval call from the previous step, if one was
needed.
```json Redeem Calls theme={null}
[
// Include the approval call first when needed.
// …
{
"target": "0x12121212006e4CD160D18e3f00711DA5c3372600",
"value": "0",
"data": ""
}
]
```
Fetch a fresh `WALLET` nonce before each submission.
```bash theme={null}
curl -G "https://relayer-v2.polymarket.com/v1/account/transactions/params" \
-H "RELAYER_API_KEY: $RELAYER_API_KEY" \
-H "RELAYER_API_KEY_ADDRESS: $RELAYER_API_KEY_ADDRESS" \
--data-urlencode "address=$RELAYER_API_KEY_ADDRESS" \
--data-urlencode "type=WALLET"
```
The response includes the nonce to sign with the transaction.
```json theme={null}
{
"address": "",
"nonce": ""
}
```
Build the Deposit Wallet EIP-712 `Batch` typed data.
```json theme={null}
{
"domain": {
"name": "DepositWallet",
"version": "1",
"chainId": 137,
"verifyingContract": ""
},
"types": {

"message": {
"wallet": "",
"nonce": "",
"deadline": "",
"calls": [
// Use the final calls array from the previous steps.
// …
]
}
}
```
Sign the EIP-712 batch with your signer. Use the resulting signature as
`signature` in the relayer submission.
Submit the signed transaction to the Relayer API.
```bash theme={null}
curl -X POST "https://relayer-v2.polymarket.com/submit" \
-H "Content-Type: application/json" \
-H "RELAYER_API_KEY: $RELAYER_API_KEY" \

"metadata": "Redeem Combo position",
"depositWalletParams": {
"depositWallet": "",
"deadline": "",
"calls": [
// Use the final calls array from the previous steps.

]
}
}'
```
The response includes the relayer transaction ID.
```json theme={null}
{
"transactionID": "",
"state": "STATE_NEW"
}
```
Poll the relayer transaction until it reaches `STATE_CONFIRMED` before relying on
the redeemed balance.
```bash theme={null}
curl "https://relayer-v2.polymarket.com/v1/account/transactions/" \
-H "RELAYER_API_KEY: $RELAYER_API_KEY" \

```
```json theme={null}
{
"transaction_id": "",
"transaction_hash": "",
"state": "STATE_CONFIRMED",
"error_msg": null
}
```
Treat `STATE_FAILED` and `STATE_INVALID` as terminal failures.
## Get Combo Markets
Use the Combo markets catalog to retrieve active markets that can be used as
Combo legs. Markets are ordered by volume descending.
Use `client.listComboMarkets(...)` to page through markets that can be used as
Combo legs.
```ts theme={null}
const paginator = client.listComboMarkets({ pageSize: 50 });
for await (const page of paginator) {
// page.items: ComboMarket[]
}
```
Use `exclude` to omit markets you have already shown or selected.
```ts theme={null}
const paginator = client.listComboMarkets({
exclude: selectedConditionIds,
pageSize: 50,
});
```
The SDK returns structured YES and NO outcomes.
```ts theme={null}
type ComboMarket = {
id: MarketId;
conditionId: CtfConditionId;
slug: string;
title: string;
outcomes: {
yes: {
label: string;
positionId: PositionId;
price: DecimalString;
};
no: {
label: string;
positionId: PositionId;
price: DecimalString;
};
};
image: string;
volume: number;
tags: string[];
};
```
Use `client.list_combo_markets(...)` to page through markets that can be used as
Combo legs.
```python theme={null}
paginator = client.list_combo_markets(page_size=50)
async for market in paginator.iter_items():
print(market.title, market.outcomes.yes.position_id)
```
Use `exclude` to omit markets you have already shown or selected.
```python theme={null}
paginator = client.list_combo_markets(
exclude=selected_condition_ids,
page_size=50,
)
```
The SDK returns structured YES and NO outcomes with snake\_case fields.
```python theme={null}
yes_position_id = market.outcomes.yes.position_id
yes_price = market.outcomes.yes.price
no_position_id = market.outcomes.no.position_id
no_price = market.outcomes.no.price
```
Fetch the first page of Combo-enabled markets.
```bash theme={null}
curl -G "https://combos-rfq-api.polymarket.com/v1/rfq/combo-markets" \
--data-urlencode "limit=50"
```
Use `cursor` to fetch the next page, and use `exclude` to omit markets you have
already shown or selected.
```bash theme={null}
curl -G "https://combos-rfq-api.polymarket.com/v1/rfq/combo-markets" \
--data-urlencode "limit=50" \
--data-urlencode "cursor=" \
--data-urlencode "exclude=,"
```
The response includes markets and an opaque `next_cursor`. A `null` cursor means
there are no more pages.
```json theme={null}
{
"markets": [
{

For each market, `position_ids`, `outcomes`, and `outcome_prices` are aligned by
array index. Index `0` is the YES outcome, and index `1` is the NO outcome.
## Map Legs to Markets
Market makers should build their own view of the markets that support Combos
before quote requests arrive. Combo-enabled markets expose a list of position
IDs with two entries: the first is the YES position ID and the second is the NO
position ID. These IDs identify the outcome positions your pricing system can map
back to market data.
Fetch non-closed markets and index them by position ID in your own market data
store.
```ts theme={null}
for await (const page of client.listMarkets({ closed: false })) {
for (const market of page.items) {
for (const positionId of market.positionIds) {
marketByPositionId.set(positionId, market);
}
}
}
```
You can also fetch markets by leg position ID on demand, but most market makers
will want this context ready before the **400 ms** quote window starts.
```ts theme={null}
const page = await client
.listMarkets({
positionIds: event.legPositionIds,
})
.firstPage();
const markets = page.items;
```
Fetch non-closed markets and index them by position ID in your own market data
store.
```python theme={null}
async for market in client.list_markets(closed=False).iter_items():
for position_id in market.position_ids:
market_by_position_id[position_id] = market
```
You can also fetch markets by leg position ID on demand, but most market makers
will want this context ready before the **400 ms** quote window starts.
```python theme={null}
page = await client.list_markets(
position_ids=event.leg_position_ids,
).first_page()
markets = page.items
```
Use Gamma `GET /markets` to resolve Combo leg position IDs into market metadata.
Build this mapping outside the quote path.
```bash theme={null}
curl -G "https://gamma-api.polymarket.com/markets" \
--data-urlencode "closed=false" \
--data-urlencode "limit=100"
```
Index every returned market by `positionIds`.
```json theme={null}
{
"id": "",
"conditionId": "",
"question": "Will example happen?",
"positionIds": ["", ""]
}
```
You can also resolve markets by leg position ID on demand, but avoid doing this
inside the **400 ms** quote window.
```bash theme={null}
curl -G "https://gamma-api.polymarket.com/markets" \
--data-urlencode "position_ids=" \
--data-urlencode "position_ids="
```
## Listen to Execution Updates
Execution updates tell you what happened after one of your quotes was selected.
Use them to reconcile RFQ state, transaction hashes, and terminal execution
outcomes in your own systems.
First, switch on `event.type` to handle execution updates from the same session
stream.
```ts theme={null}
switch (event.type) {
case "execution_update":
// event: RfqExecutionUpdateEvent
handleExecutionUpdate(event);
break;
// …
}
```
Then, inspect the execution update before reconciling the selected RFQ. Execution
updates are correlated by `rfqId`.
```ts theme={null}
type RfqExecutionUpdateEvent = {
type: "execution_update";
rfqId: RfqId;
status: RfqExecutionStatus;
txHash?: TxHash;
};
```
where `RfqExecutionStatus` could be:
| Status | Meaning |
| ------------------------------ | ------------------------------------------------- |
| `RfqExecutionStatus.Matched` | The quote was selected and handed off to execute. |
| `RfqExecutionStatus.Mined` | The execution transaction was mined. |
| `RfqExecutionStatus.Retrying` | Execution is being retried. |
| `RfqExecutionStatus.Confirmed` | Execution completed successfully. |
| `RfqExecutionStatus.Failed` | Execution failed. |
Finally, persist the update and treat `RfqExecutionStatus.Confirmed` and
`RfqExecutionStatus.Failed` as terminal states.
```ts theme={null}
function handleExecutionUpdate(event: RfqExecutionUpdateEvent) {
storeExecutionUpdate(event);
if (event.status === RfqExecutionStatus.Confirmed) {
markQuoteConfirmed(event.rfqId);
return;
}
if (event.status === RfqExecutionStatus.Failed) {
markQuoteFailed(event.rfqId);
}
}
```
First, use `isinstance(...)` to handle execution updates from the same session
stream.
```python theme={null}
from polymarket import RfqExecutionUpdateEvent
async for event in session:
if isinstance(event, RfqExecutionUpdateEvent):
handle_execution_update(event)
```
Then, inspect the execution update before reconciling the selected RFQ. Execution
updates are correlated by `rfq_id`.
```python theme={null}
class RfqExecutionUpdateEvent:
type: "execution_update"
rfq_id: RfqId
status: RfqExecutionStatus
tx_hash: TransactionHash | None
```
where `RfqExecutionStatus` could be:
| Status | Meaning |
| ------------------------------ | ------------------------------------------------- |
| `RfqExecutionStatus.MATCHED` | The quote was selected and handed off to execute. |
| `RfqExecutionStatus.MINED` | The execution transaction was mined. |
| `RfqExecutionStatus.RETRYING` | Execution is being retried. |
| `RfqExecutionStatus.CONFIRMED` | Execution completed successfully. |
| `RfqExecutionStatus.FAILED` | Execution failed. |
Finally, persist the update and treat `RfqExecutionStatus.CONFIRMED` and
`RfqExecutionStatus.FAILED` as terminal states.
```python theme={null}
from polymarket import RfqExecutionStatus, RfqExecutionUpdateEvent
def handle_execution_update(event: RfqExecutionUpdateEvent) -> None:
store_execution_update(event)
if event.status is RfqExecutionStatus.CONFIRMED:
mark_quote_confirmed(event.rfq_id)
return
if event.status is RfqExecutionStatus.FAILED:
mark_quote_failed(event.rfq_id)
```
Listen for `RFQ_EXECUTION_UPDATE` messages on the RFQ WebSocket after one of your
quotes is selected.
```json theme={null}
{
"type": "RFQ_EXECUTION_UPDATE",
"rfq_id": "",
"status": "MINED",
"tx_hash": ""
}
```
Execution updates are correlated by `rfq_id`.
| Status | Meaning |
| ----------- | ------------------------------------------------- |
| `MATCHED` | The quote was selected and handed off to execute. |
| `MINED` | The execution transaction was mined. |
| `RETRYING` | Execution is being retried. |
| `CONFIRMED` | Execution completed successfully. |
| `FAILED` | Execution failed. |
Treat `CONFIRMED` and `FAILED` as terminal states.
## Listen to Trade Broadcasts
Confirmed trade broadcasts tell connected market makers when any Combo RFQ trade
has completed successfully. Use them to build a public trade tape, update risk,
or reconcile market activity that was filled by another maker.
Trade broadcasts are best-effort and may be replayed after reconnects. Deduplicate
them by RFQ ID: `rfqId` in TypeScript or `rfq_id` in Python and raw WebSocket
messages.
First, switch on `event.type` to handle trade broadcasts from the same session
stream.
```ts theme={null}
switch (event.type) {
case "trade":
// event: RfqTradeEvent
handleTrade(event);
break;
// …
}
```
Then, inspect the confirmed trade before storing or applying it. Trade broadcasts
exclude maker identity and per-maker fill allocations.
```ts theme={null}
type RfqTradeEvent = {
type: "trade";
rfqId: RfqId;
requesterId: RfqRequestorPublicId;
conditionId: ComboConditionId;
legPositionIds: PositionId[];
direction: RfqDirection;
side: RfqSide.Yes;
price: DecimalString;
size: DecimalString;
executedAt: EpochMilliseconds;
};
```
`price` is the accepted blended price in pUSD per YES Combo share. `size` is the
matched Combo share size. Both values are normalized decimal strings.
Finally, persist the trade by RFQ ID and execution timestamp for downstream
reconciliation.
```ts theme={null}
function handleTrade(event: RfqTradeEvent) {
storeComboTrade({
rfqId: event.rfqId,
conditionId: event.conditionId,
legPositionIds: event.legPositionIds,
requesterId: event.requesterId,
price: event.price,
size: event.size,
executedAt: event.executedAt,
});
}
```
First, use `isinstance(...)` to handle trade broadcasts from the same session
stream.
```python theme={null}
from polymarket import RfqTradeEvent
async for event in session:
if isinstance(event, RfqTradeEvent):
handle_trade(event)
```
Then, inspect the confirmed trade before storing or applying it. Trade broadcasts
exclude maker identity and per-maker fill allocations.
```python theme={null}
from decimal import Decimal
class RfqTradeEvent:
type: "trade"
rfq_id: RfqId
requester_id: RfqRequestorPublicId
condition_id: ComboConditionId
leg_position_ids: tuple[PositionId, ...]
direction: RfqDirection
side: RfqSide
price: Decimal
size: Decimal
executed_at: int
```
`price` is the accepted blended price in pUSD per YES Combo share. `size` is the
matched Combo share size. Both values are `Decimal` instances.
Finally, persist the trade by RFQ ID and execution timestamp for downstream
reconciliation.
```python theme={null}
from polymarket import RfqTradeEvent
def handle_trade(event: RfqTradeEvent) -> None:
store_combo_trade(
rfq_id=event.rfq_id,
condition_id=event.condition_id,
leg_position_ids=event.leg_position_ids,
requester_id=event.requester_id,
price=event.price,
size=event.size,
executed_at=event.executed_at,
)
```
Listen for `RFQ_TRADE` messages on the RFQ WebSocket after Combo executions are
confirmed. These messages are sent to authenticated quoter sessions and exclude
maker identity and per-maker fill allocations.
```json theme={null}
{
"type": "RFQ_TRADE",
"rfq_id": "",
"requester_id": "",
"condition_id": "",
"leg_position_ids": ["", ""],
"direction": "BUY",
"side": "YES",
"price_e6": "125000",
"size_e6": "800000",
"executed_at": 1780854786039
}
```
`price_e6` is the accepted blended price in 6-decimal base units, and `size_e6`
is the matched Combo share size in 6-decimal base units.
## Handle Errors
In this section, we will talk you through how to handle errors with the RFQ system.
### Open the RFQ Session
Wrap `client.openRfqSession()` in `try`/`catch` and use
`OpenRfqSessionError.isError(…)` to narrow the error type.
```ts theme={null}
try {
const session = await client.openRfqSession();
} catch (error) {
if (!OpenRfqSessionError.isError(error)) throw error;
switch (error.name) {
case "TransportError":
// error: TransportError
break;
}
}
```
### Submit a Quote
Wrap `event.quote(…)` in `try`/`catch` and use `RfqQuoteError.isError(…)` to
narrow the error type.
```ts theme={null}
try {
const reference = await event.quote({ price });
// …
} catch (error) {
if (!RfqQuoteError.isError(error)) throw error;
switch (error.name) {
case "RfqQuoteRejectedError":
// error: RfqQuoteRejectedError
// error.rfqId: RfqId
// error.code: RfqErrorCode | undefined
break;
case "SigningError":
// error: SigningError
break;
case "TimeoutError":
// error: TimeoutError
break;
case "TransportError":
// error: TransportError
break;
case "UserInputError":
// error: UserInputError
break;
}
}
```
### Cancel a Quote
Wrap `session.cancelQuote(…)` in `try`/`catch` and use
`RfqCancelQuoteError.isError(…)` to narrow the error type.
```ts theme={null}
try {
const ack = await session.cancelQuote(reference);
// …
} catch (error) {
if (!RfqCancelQuoteError.isError(error)) throw error;
switch (error.name) {
case "RfqCancelQuoteRejectedError":
// error: RfqCancelQuoteRejectedError
// error.rfqId: RfqId
// error.quoteId: RfqQuoteId
// error.code: RfqErrorCode | undefined
break;
case "TimeoutError":
// error: TimeoutError
break;
case "TransportError":
// error: TransportError
break;
}
}
```
### Confirm or Decline
Wrap `event.confirm()` or `event.decline()` in `try`/`catch` and use
`RfqConfirmationError.isError(…)` to narrow the error type.
```ts theme={null}
try {
if (canStillFill) {
await event.confirm();
} else {
await event.decline();
}
} catch (error) {
if (!RfqConfirmationError.isError(error)) throw error;
switch (error.name) {
case "RfqConfirmationRejectedError":
// error: RfqConfirmationRejectedError
// error.rfqId: RfqId
// error.quoteId: RfqQuoteId
// error.code: RfqErrorCode | undefined
break;
case "TimeoutError":
// error: TimeoutError
break;
case "TransportError":
// error: TransportError
break;
}
}
```
### Open the RFQ Session
Wrap `client.open_rfq_session()` in `try`/`except` and catch SDK exception types.
```python theme={null}
from polymarket import TimeoutError, TransportError
try:
async with client.open_rfq_session() as session:
async for event in session:
...
except TimeoutError as error:
# error: TimeoutError
...
except TransportError as error:
# error: TransportError
...
```
### Submit a Quote
Wrap `event.quote(...)` in `try`/`except` and catch the typed RFQ rejection,
timeout, and transport errors.
```python theme={null}
from decimal import Decimal
from polymarket import RfqQuoteRejectedError, TimeoutError, TransportError
try:
reference = await event.quote(price=Decimal("0.45"))
except RfqQuoteRejectedError as error:
# error.rfq_id: RfqId
# error.code: RfqErrorCode | None
...
except TimeoutError as error:
# error: TimeoutError
...
except TransportError as error:
# error: TransportError
...
```
### Cancel a Quote
Wrap `session.cancel_quote(...)` in `try`/`except` and catch the typed RFQ
cancellation rejection, timeout, and transport errors.
```python theme={null}
from polymarket import RfqCancelQuoteRejectedError, TimeoutError, TransportError
try:
ack = await session.cancel_quote(reference)
except RfqCancelQuoteRejectedError as error:
# error.rfq_id: RfqId
# error.quote_id: RfqQuoteId
# error.code: RfqErrorCode | None
...
except TimeoutError as error:
# error: TimeoutError
...
except TransportError as error:
# error: TransportError
...
```
### Confirm or Decline
Wrap `event.confirm()` or `event.decline()` in `try`/`except` and catch the typed
RFQ confirmation rejection, timeout, and transport errors.
```python theme={null}
from polymarket import RfqConfirmationRejectedError, TimeoutError, TransportError
try:
if can_still_fill:
await event.confirm()
else:
await event.decline()
except RfqConfirmationRejectedError as error:
# error.rfq_id: RfqId
# error.quote_id: RfqQuoteId
# error.code: RfqErrorCode | None
...
except TimeoutError as error:
# error: TimeoutError
...
except TransportError as error:
# error: TransportError
...
```
When a WebSocket command fails validation or cannot be applied, the RFQ system
sends `RFQ_ERROR`.
```json theme={null}
{
"type": "RFQ_ERROR",
"request_type": "RFQ_QUOTE",
"rfq_id": "",
"quote_id": "",
"code": "SUBMISSION_WINDOW_CLOSED",
"error": "submission window closed"
}
```
Use `request_type`, `rfq_id`, and `quote_id` to correlate the error with the
command you sent.
| Field | Description |
| -------------- | ----------------------------------------------- |
| `type` | Always `RFQ_ERROR` |
| `request_type` | Inbound command that failed, when parsed |
| `rfq_id` | RFQ ID, when present on the failed command |
| `quote_id` | Quote ID, when present on the failed command |
| `code` | Stable machine-readable error code |
| `error` | Human-readable detail for logging and debugging |
The `request_type` value identifies the command that failed.
| `request_type` | Failed command |
| --------------------------- | --------------------------------- |
| `RFQ_QUOTE` | Quote submission |
| `RFQ_QUOTE_CANCEL` | Quote cancellation |
| `RFQ_CONFIRMATION_RESPONSE` | Last Look confirmation or decline |
Error codes include:
| Code | Meaning |
| ------------------------------------------ | -------------------------------------------------------------- |
| `INVALID_MESSAGE` | Message JSON or message type is invalid |
| `UNAUTHORIZED_ROLE` | Message is not allowed for the authenticated gateway role |
| `ADDRESS_MISMATCH` | Message identity does not match the authenticated session |
| `UNKNOWN_RFQ` | RFQ ID is not active or no longer exists |
| `EXPIRED_RFQ` | RFQ has expired |
| `SUBMISSION_WINDOW_CLOSED` | Quote arrived after the submission window closed |
| `ALLOWANCE_VALIDATION_FAILED` | Maker allowance is insufficient for the quoted order |
| `BALANCE_VALIDATION_FAILED` | Maker balance is insufficient for the quoted order |
| `PRE_EXECUTION_BALANCE_RESERVATION_FAILED` | Balance reservation failed before execution |
| `INVALID_QUOTE` | Quote payload or signed order is invalid |
| `INVALID_RFQ_STATE` | RFQ is not in a state that accepts the requested command |
| `INVALID_CONFIRMATION` | Last Look confirmation payload is invalid |
| `MAKER_NOT_REQUIRED` | This quote maker is not required for last-look confirmation |
| `MAKER_ALREADY_RESPONDED` | This quote maker already responded to the confirmation request |
| `SERVICE_UNAVAILABLE` | RFQ service dependency is temporarily unavailable |
Treat these errors as command-level failures. Keep the WebSocket session alive
unless the connection itself closes or authentication fails.
