# Cancel all orders

> Cancel every active limit order on your account, optionally scoped to a single event or market.

Cancel all active limit orders for the authenticated user in one call. You can scope the cancellation to a specific event or market — useful when you want to retire a single ladder or quickly unwind your exposure on one outcome without touching the rest of your book.

## Endpoint

```
POST https://api.futuur.com/orders/cancel-all/
```

## Authentication

<Note>
  This endpoint requires HMAC authentication. Include the `Key`, `Timestamp`, and `HMAC` headers on every request. See the [authentication guide](/authentication) for signing instructions.
</Note>

## Request

The request body is optional. If you submit an empty body, every active order on your account is canceled.

<ParamField body="event" type="integer">
  Limit the cancellation to orders on a specific event (question) ID.
</ParamField>

<ParamField body="market" type="integer">
  Limit the cancellation to orders on a specific market (outcome) ID. Can be combined with `event` to scope further.
</ParamField>

## Response

Returns `200 OK` with two arrays of order IDs.

<ResponseField name="canceled_order_ids" type="integer[]" required>
  IDs of orders that were successfully canceled.
</ResponseField>

<ResponseField name="processing_order_ids" type="integer[]" required>
  IDs of orders that could not be canceled immediately because they were already being processed (for example, mid-fill). Retry these IDs with [Batch cancel](/api-reference/orders/batch-cancel) after a short delay if you need them removed.
</ResponseField>
