# Cancel a Review Execution

> POST /api/open/v1/projects/:projectId/reviews/:reviewId/executions/:executionId/cancel — requests cancellation of a durable review execution.

Request cancellation using the public review and execution IDs. Your API key needs the `reviews:write` scope.

## Endpoint

```http theme={null}
POST https://plangrep.com/api/open/v1/projects/{projectId}/reviews/{reviewId}/executions/{executionId}/cancel
```

A `202 Accepted` response includes `cancellationRequested: true`. Keep polling the execution until it reports `cancelled`; cancellation is asynchronous. If the execution is already terminal, the endpoint returns its current state with `idempotent: true`.

The contract never asks you to provide, store, or poll an internal container job ID.
