# Cancel Turn

`POST /v1/ask-feather/sessions/{session_id}/turns/{turn_id}/cancel`

Stop button (Q11): set the Redis cancel flag for a turn the caller owns; the
worker finalizes ``cancelled`` at the next node boundary. Idempotent — a cancel
for an already-finished turn just sets a flag that self-expires.

## Path parameters

- `session_id` string, uuid, required
- `turn_id` string, uuid, required

## Response `202`

Successful Response

- object

## Other responses

- `422` — Validation Error
