# Cancel Bulk Sync Execution

`POST /api/bulk/syncs/{id}/executions/{exec_id}/cancel`

Requests cancellation of a specific bulk sync execution.

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

## Path parameters

- `id` string, uuid, required — The bulk sync ID.
- `exec_id` string, uuid, required — The execution ID to cancel.

## Headers

- `X-Polytomic-Version` string

## Response `200`

OK

- CancelBulkSyncResponseEnvelope
  - `data` CancelBulkSyncResponse
    - `message` string

## Other responses

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