Webhook event ID deduplication patterns
Providers may deliver the same logical event more than once. Store a unique event or delivery ID with outcome status so retries are safe and measurable.
Common causes
- Idempotency only on HTTP method and path.
- Database unique constraint missing.
- TTL shorter than provider retry horizon.
How to fix
- Use UUID Generator for new internal correlation IDs.
- Key idempotency on provider event ID.
- Monitor duplicates with Latency Checker dashboards.
