# Cancel order

> Partner cancels the order.

POST`https://api.maple.inc/v1/orders/{orderId}/cancel`API key

## Authorization

Send your API key as `Authorization: Bearer <key>`: `mpk_test_…` against the sandbox (`https://api.staging.maple.inc/v1`), `mpk_live_…` against production. See [Authentication](https://docs.maple.inc/developer-api/concepts/authentication.md). The samples read the key from `MAPLE_KEY` and the base URL from `MAPLE_BASE`, as set up in the [Quickstart](https://docs.maple.inc/developer-api/quickstart.md).

## Parameters

- `orderId` string path required

## Request body

`application/json`, required.

- `reason` string or null

## Responses

### 200 OK

- `object` string required

  Always `order_decision`.

- `order_id` string required

- `decision` string required

  One of `accept`, `deny`, `ready`, `complete`, `cancel`, `status`.

- `status` string required

  Always `received`.

### Errors

- `400` Bad request DeveloperApiBadRequest

- `401` Unauthorized DeveloperApiUnauthorized

- `403` Forbidden DeveloperApiForbidden

- `404` Not found DeveloperApiNotFound

- `429` Too many requests DeveloperApiRateLimited

Every error body names the error in `_tag`, explains it in `message`, and says where to report it in `feedback`. See [Errors](https://docs.maple.inc/developer-api/concepts/errors.md).

A `429` also sends `Retry-After`: Seconds to wait before retrying; also returned as retry\_after in the body.
