<CodeGroup>
  ```bash cURL theme={null}
  curl -X POST "https://api.rebelfi.io/v1/operations/123/cancel" \
    -H "x-api-key: your_api_key"
  ```

  ```typescript SDK theme={null}

### Errors

| Code                       | Description                                                   |
| -------------------------- | ------------------------------------------------------------- |
| `OPERATION_NOT_FOUND`      | Operation ID doesn't exist                                    |
| `INVALID_OPERATION_STATUS` | Operation has already been submitted, confirmed, or cancelled |

<Tip>
  In most cases you don't need to cancel manually. Simply create a new operation — any pending operations for the same wallet are automatically cancelled.
