ai.operation.completed

An async AI run (review response, message draft, pricing suggestion) finished.

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.

  }
}

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.

Use the raw body

Sign the raw request body exactly as received, not a re-stringified JSON object. Re-serialisation can reorder keys or change whitespace and break the signature.

Tip: Acknowledge with a 2xx status within 10 seconds. Failed deliveries are retried up to 5 times with exponential backoff.Webhook reliability →
