Events & webhooks
The asynchronous truth trail. Every state change emits a CloudEvents-style envelope. Subscribers receive signed deliveries with retry, replay, and signature rotation.
Envelope
CloudEvents 1.0 envelope; type follows domain.action; subject carries the prefixed resource id.
Delivery contract
- HTTPS POST to your registered endpoint. Signed via HMAC; secret rotates without downtime.
- Exponential-backoff retries up to 24h; manual replay available.
- At-least-once delivery — consumers must dedupe by
id.
