# Cancel a run

`POST /agent/runs/{runId}/cancel`

Cancel an agent run that is currently queued or in progress.
Once cancelled, the run will transition to a cancelled state.

Not all runs can be cancelled. Runs that are in a terminal state
(SUCCEEDED, FAILED, ERROR, BLOCKED, CANCELLED) return 400. Runs in
PENDING state return 409 (retry after a moment). Self-hosted, local,
and GitHub Action runs return 422.

## Path parameters

- `runId` string, required

## Response `200`

Run cancelled successfully

- string — The ID of the cancelled run

## Other responses

- `400` — Missing run ID, or the run is already in a terminal state (error_code: invalid_request)
- `401` — Authentication required
- `403` — No permission to cancel run
- `404` — Run not found
- `409` — Run is in PENDING state and cannot be cancelled yet. Retry after a moment (error_code: conflict, retryable: true).
- `422` — Run cannot be cancelled because the operation is not supported for this run type (e.g., self-hosted, local, or GitHub Action runs) (error_code: operation_not_supported)
