What Actually Happens After You Send a Webhook
TL;DR: A practical look at how webhooks fail and recover in production, emphasizing delivery mechanics over simple HTTP retries.
Webhooks are a durable state machine with retry policies, idempotency, and signing. Real issues emerge in delivery logistics: queues, retries, timeouts, and deduplication. A simulator demonstrates failures, retries, and how to verify signatures before parsing. The message highlights best practices: sign IDs/timestamps, verify first, and understand at-least-once delivery. The simulator mirrors real-world behavior (Svix retry schedule and signing) to map to production.
Question for the room: What is your approach to ensuring idempotent webhook processing in your system?
