# Cancel Response

`DELETE /v1/omni-ai/responses/{response_id}`

## Request

- Base URL: `https://api.clearstreet.com`
- URL: `https://api.clearstreet.com/v1/omni-ai/responses/{response_id}`
- Auth: HTTP bearer

Cancel a queued or running response. Canceling a running response (Stop)
also cancels every queued response in the thread that answers a user
message. Canceling a queued response (withdraw) cancels only that response;
the running response and other queued responses continue. Cancellation is
idempotent after the response becomes terminal. Each canceled response
still produces a finalized assistant message with outcome `canceled` in the
thread history. Canceling a response that ended `steered` or `merged`
stops the response that continues its work, with the same effect as Stop.

Authorization uses the linked account before any cancellation.
