Receiving guide
Implement and test your webhook receiver end to end.
Build a reliable receiver
- Authenticate and validate every incoming request before processing it.
- Return a successful response quickly, then perform slow work asynchronously.
- Make handlers idempotent so retries never duplicate customer-visible effects.
- Record event identifiers and processing outcomes for operational debugging.
