webhook-reliability

To handle duplicate webhook deliveries, you enforce idempotent processing by deduplicating inbound payloads using a stable delivery ID. This ensures that processing the same webhook event multiple times yields the same result without duplicating side effects.

The best way to prevent webhook timeouts is to accept inbound payloads immediately and process them asynchronously. By enqueueing the payload for a background worker, you avoid blocking the provider's HTTP request and hitting their timeout limits.

You configure outbound webhook retries using a worker-driven processing model with customizable retry policies. This approach applies exponential backoff to failed delivery attempts, ensuring at-least-once delivery to customer endpoints.

You should move failed webhook deliveries to a dead-letter queue (DLQ) after exhausting all configured retry attempts. Triggering alerts upon dead-lettering ensures operator visibility for endpoints that consistently fail to accept outbound events.

Signature validation secures inbound webhook ingestion by cryptographically verifying the payload against the provider's signature before enqueuing. This prevents unauthorized or tampered requests from entering your reliable delivery processing pipeline.

Yes, you need a dedicated worker-driven processing model to guarantee reliable webhook delivery. The worker manages the queue, executes retry policies with backoff, and handles dead-letter queueing, ensuring at-least-once delivery for both inbound and outbound events.
