What should a webhook endpoint do before processing an event?

It should validate the signature, timestamp, source account, event type, payload version, and target environment, then persist the delivery and enqueue valid work before any business mutation happens.

How do webhook retries avoid duplicate customer actions?

Retries stay safe when the system deduplicates by event and business object, uses idempotency keys for side effects, stores processing state, and treats replayed events like original deliveries with the same validation and audit path.

When does a webhook need a dead-letter queue?

A dead-letter queue is needed when failed events affect business state, customers, payments, notifications, provisioning, reporting, or support. It gives operators a visible place to review, replay, skip, escalate, or reconcile failures safely.
