Webhook retries and delivery failures

Queued delivery

Webhook events are queued and delivered by cron rather than blocking the conversion callback.

Retry behavior

Temporary failures are retried with backoff. Your endpoint should return a successful 2xx response only after it has safely accepted the event.

Make your endpoint idempotent

Retries are normal in distributed systems. Design the receiving endpoint so the same event can arrive more than once without duplicate user credit.
