Cancel a run

POST/api/v3/run/{id}/cancel

Overview

No request body. Cancels only queued runs that have never been admitted or dispatched. Admission and cancellation are serialized atomically. Running/outcome-unknown work returns 409 run_not_cancelable. Already terminal runs return their current snapshot with 200, including outputs if applicable. Repeating cancellation needs no Idempotency-Key. A newly canceled run releases its commitment and emits its configured terminal webhook once (delivery retries remain possible). Foreign or non-v3 runs return 404.

Requires an API key. Send Authorization: Bearer YOUR_API_KEY. Authentication →
