ai.operation.failed

An async AI run terminated with an error and will not be retried.

Payload

Every delivery uses the same outer envelope (event, eventId, apiVersion, timestamp, data). Dedupe on eventId — it stays stable across retries and replays, while the X-Repull-Delivery-Id header changes on every attempt.

{
  "event": "ai.operation.failed",
  "eventId": "3f1c9a2e-8b7d-4c6a-9e0f-1a2b3c4d5e6f",

  "timestamp": "2026-05-01T12:34:56.000Z",

  }
}

Verifying signatures

Every delivery includes a timestamped X-Repull-Signature header of the form t=<unix_ts>,v1=<hex>, where v1 is HMAC-SHA256(signing_secret, `${t}.${raw_body}`). Verify it before processing — see Verify Signatures for full Node.js and Python examples.
