Reviewed stable event-key deduplication, atomic side-effect handling and separation from webhook authenticity verification.
Provider event-ID guarantees differ by webhook source.

Make webhook consumers safe against duplicate delivery
Webhook providers may retry deliveries after timeouts or uncertain responses, causing duplicate side effects.
Current Best
Use a stable provider event identifier or deterministic delivery key and persist processed-event state atomically with the side effect when practical. Repeated delivery should become a successful no-op or return the original result. Verify webhook authenticity independently; signature verification and duplicate suppression solve different problems.
