# Cancel futures orders (not yet implemented)

> Returns HTTP 501. Nothing can be cancelled while nothing can be placed — see `POST /futures/place-orders`.



## OpenAPI

````yaml /zh/abp-api/openapi.json post /futures/cancel-orders
openapi: 3.1.0
info:
  title: ABP v2 - Automated Bet Placing API
  description: >

    Place bets across 36 bookmakers through a single API.


    ## Authentication


    All endpoints require the `x-api-key` header (except `/health`, `/ready`,
    `/status`, `/metrics`).


    **Swagger UI**: Click the **Authorize** button (lock icon) at the top right,
    enter your API key, and click **Authorize**.


    ## Two surfaces: fixtures and futures


    Selections come in two kinds and each has its own path prefix, so no
    endpoint has to guess which identifiers it was given:


    | | Fixtures | Futures (outrights) |

    |---|---|---|

    | Prefix | `/fixtures/*` | `/futures/*` |

    | Selection | `fixtureId` + `outcomeId` + `playerId` | `futureId` +
    `futureOutcomeId` + `participantId` |

    | Status | fully live | reads live; placement and order/bet reads answer
    `501` |


    Each surface **rejects the other's identifiers** with `422`. The pre-split
    unprefixed paths (`/betslip`, `/place-orders`, `/orders`, `/bets`,
    `/markets`, …) still work unchanged and are listed here as deprecated
    aliases of their `/fixtures/*` equivalents.


    `/accounts`, `/bookmakers`, `/positions` and `/pnl` name no selection and
    stay unprefixed.


    ## Quick Start


    1. **List your accounts**: `GET /accounts`

    2. **Get live odds**: `GET
    /fixtures/betslip?fixtureId=...&outcomeId=...&playerId=0`

    3. **Place an order**: `POST /fixtures/place-orders`

    4. **Track results**: `GET /fixtures/orders` or subscribe to WebSocket
    updates


    ## WebSocket


    Connect to `/ws` for real-time order, bet, and settlement updates.


    ```json

    {"type": "login", "apiKey": "your-api-key", "channels": []}

    ```


    Send an empty `channels` array to receive all updates. Available channels:
    `orders`, `bets`, `settlements`, `accounts`, `balance`, `betslip`,
    `fixtures`, `currencies`, `status`, `emergency`.


    Send `{"type": "ping"}` every 30 seconds to keep the connection alive.
