fasthook is a webhook gateway that sits between webhook producers (like Stripe, GitHub, Shopify) and your application. It receives, verifies, stores, routes, transforms, retries, and replays webhook events — giving teams a reliable delivery layer before failures reach application code.
Returning 200 OK doesn't guarantee a webhook was processed. Downstream APIs can time out, return 429 or 5xx, credentials rotate, payload schemas change, and retries can cause duplicate side effects. fasthook persists every request, traces each destination attempt, and keeps retries and replay close to the logs engineers need during recovery.
fasthook is for developers and platform teams that operate production webhook integrations for billing, repositories, commerce, support, or internal automation. It's also useful for testing webhooks with temporary request bins. It is not for teams that only need a simple webhook catcher — fasthook focuses on the operational path: capture, route, inspect, retry, replay.
Route one source (e.g., Stripe) to multiple destinations (CRM, billing, analytics) with filters and transformations. Debug a failed delivery by inspecting request, event, and attempt history. Replay failed deliveries after a receiver or credential recovers. Test webhooks with a temporary bin before building a full workflow.
