Also served at `/v1/gateway/cancel-wallet-orders`. Only the wallet owner can call this endpoint. Send L2 headers with `POLY_ADDRESS` set to the owner EOA and the owner's API key. Session signers receive 403 and must use `DELETE /order`, `DELETE /orders` or `DELETE /cancel-all`, which only cancel orders placed with their own API key. Set exactly one of `order_ids` or `all`. Unknown orders, orders from another maker, and already canceled orders are returned in `not_canceled` with the reason `order not found on the caller's deposit wallet`. Shares the cancel rate-limit bucket with `DELETE /orders` and `DELETE /cancel-all`. With `order_ids`, each ID costs one token up front. With `all`, the request costs one token up front and is then charged for the number of orders actually canceled. Revoking a session signer immediately triggers the relayer to cancel its open orders. After cancellation, canceling those IDs returns them in `not_canceled`. Authorization and revocation changes can take up to about 5 seconds to appear here. Production rollout: this route currently returns an nginx 404 page until load-balancer routing is enabled. The production feature flag must also be enabled. A disabled application endpoint returns a JSON 404 response instead. ## OpenAPI ````yaml /api-spec/clob-openapi.yaml delete /cancel-wallet-orders openapi: 3.1.0 info: title: Polymarket CLOB API description: Polymarket CLOB API Reference license: name: MIT identifier: MIT version: 1.0.0 servers: - url: https://clob.polymarket.com description: Production CLOB API - url: https://clob-staging.polymarket.com description: Staging CLOB API security: [] tags: - name: Trade description: Trade endpoints - name: Markets description: Market data endpoints - name: Account description: Account and authentication endpoints - name: Notifications description: User notification endpoints - name: Rewards description: Rewards and earnings endpoints - name: Rebates description: Maker rebate endpoints paths: /cancel-wallet-orders: delete: tags: - Trade summary: Cancel wallet orders description: > Cancels orders on the deposit wallet across all API keys, including orders from expired session signers.
