Resources
Build more reliable webhook systems
Practical engineering resources for the failure modes every webhook consumer eventually hits: debugging failed deliveries, designing retry strategies, preventing duplicate side effects, verifying signatures, and operating webhook infrastructure safely.
Featured guides
Start with the problems that page you
Deep, step-by-step guides to the three failure modes behind most webhook incidents: deliveries that fail, retries that misbehave, and duplicates that double-process.
Debugging How to Debug Failed Webhooks: A Step-by-Step Guide A systematic walkthrough for diagnosing failed webhook deliveries: connectivity, status codes, timeouts, signatures, handler exceptions, and a production debugging checklist. 9 min read Security How to Verify Webhook Signatures in Go, Node.js and Python Verify webhook signatures correctly with HMAC: the raw-body requirement, timestamped signatures and replay windows, constant-time comparison, secret rotation, and working code in Go, Node.js and Python. 10 min read Idempotency Webhook Idempotency: Preventing Duplicate Payments and Actions Duplicate webhook deliveries are normal, not a bug. How to make handlers idempotent with event IDs, a processed-events table, database uniqueness, correct transaction boundaries, and production Go — so replays and retries never charge a customer twice. 11 min read

Integrations
Provider-specific webhook guides
How to receive, verify, and troubleshoot webhooks from the platforms teams integrate most — including each provider's signature scheme and retry behaviour.

Comparisons
Choosing a webhook reliability approach
Neutral, dimension-by-dimension comparisons of the ways teams handle webhook debugging and delivery reliability — including when building it yourself is the right call.
- Comparison HookWatch vs Ngrok Comparing generic local-dev tunnels with dedicated webhook reliability infrastructure: ephemeral local exposure versus persistent delivery capture, failure grouping, and safe replay. 2 min read
- Comparison HookWatch vs Webhook.site Disposable request inspection versus production webhook reliability: comparing one-off debug bins with persistent capture, incidents, Slack alerts, and replay. 2 min read
- Comparison HookWatch vs Building In-House An honest comparison of adopting HookWatch versus building your own webhook ingestion, retry, and replay system — engineer-time, maintenance, security, and the cases where an internal build is the right call. 10 min read
- Comparison HookWatch vs Hookdeck Two inbound-webhook tools with different centres of gravity: Hookdeck as an event gateway for queueing and routing, HookWatch focused on capture, failure debugging, incidents, and safe replay — with honest overlap. 6 min read
- Comparison HookWatch vs RequestBin-Style Tools When an ephemeral request bin is exactly the right tool for inspecting a webhook payload, and when you need persistent delivery history, retries, and replay instead. 7 min read
- Comparison HookWatch vs Svix Sending versus receiving: Svix is primarily infrastructure for platforms that send webhooks to their customers, while HookWatch is for teams receiving webhooks. Different problems that often coexist. 6 min read

See what happened to every webhook
Everything in these resources leans on one capability: seeing the delivery. HookWatch records every request, response, and attempt, and gives you retry controls and safe replay when things go wrong.
