Webhooks and Event Processing
Process third-party callbacks safely despite retries, delays, and ordering issues.
Recommended approach
- Verify webhook signatures.
- Persist raw payload and processing status.
- Process events idempotently and asynchronously.
Alternatives and when to choose them
- Synchronous webhook processing only for trivial low-volume use cases.
- Event bus fan-out when multiple downstream consumers need the same event.
Implementation checklist
- Add event deduplication keys.
- Add replay tooling for failed events.
- Track processing latency and failure rates.
Common pitfalls
- Assuming webhook ordering is guaranteed.
- No forensic log for payload + processing outcome.
