# Cancel Sync

`POST /api/syncs/{id}/cancel`

Requests cancellation of any running executions on a model sync.

Cancellation is asynchronous. A successful response means the cancellation
signal has been queued; the running execution continues until the signal is
processed. Poll `GET /api/syncs/{id}/status` until the current execution
reaches a terminal state (`completed`, `canceled`, or `failed`) to confirm
cancellation has taken effect.

## Path parameters

- `id` string, uuid, required — The active execution of this sync ID will be cancelled.

## Headers

- `X-Polytomic-Version` string

## Response `200`

OK

- CancelSyncResponseEnvelope
  - `data` CancelSyncResponse
    - `message` string

## Other responses

- `403` — Forbidden
- `404` — Not Found
- `500` — Internal Server Error
