Deep dives into webhook engineering, cost analysis, architectural patterns, and practical guides from the team building GetHook.

All three move data between systems asynchronously, but they operate at different layers, make different reliability guarantees, and break in completely different ways. Here's how to pick the right tool — and when to combine them.
Rotating a webhook signing secret without dropping events or breaking consumer integrations requires more than swapping a value in your config. Here's the dual-secret overlap pattern that lets you rotate safely, with no coordination window required.
Offset-based pagination breaks under high insert rates and makes reliable event replay nearly impossible. Here's how cursor-based pagination fixes both problems and what your API and replay infrastructure should look like.
Webhook payloads routinely contain personal data — email addresses, order details, user IDs. Under GDPR, storing that data indefinitely is a liability. Here's a practical framework for what to log, how long to keep it, and how to delete it without breaking your replay guarantees.
Fanout sounds simple — receive one event, deliver to many destinations. In practice it surfaces ordering problems, partial failure scenarios, and queue design challenges that aren't obvious until you're debugging at 2am.
When your system receives webhooks from Stripe, GitHub, Twilio, and Shopify simultaneously, you need more than just a pile of endpoints. Fan-in architecture gives you a single, normalized event stream with unified retry, deduplication, and observability.
Most teams operate webhook infrastructure without any formal delivery SLA — until a customer contract demands one. Here's how to define meaningful SLA targets, instrument your system to measure them, and know when you're violating them before your customers do.
Webhook failures are hard to debug because the event touches multiple services before it either delivers or dies. Here's how to wire OpenTelemetry end-to-end so you can follow a single webhook from ingest to delivery in one trace waterfall.
Polling is the training wheels of API integrations. Here's how to replace it with a production-grade webhook integration — without dropping events during the cutover.
When Stripe sends 40,000 events in 90 seconds because your Black Friday sale just started, your webhook infrastructure needs a plan. Here's how to absorb traffic spikes without dropping events or overwhelming your downstream services.
Webhooks are notoriously hard to test in automated pipelines — they're async, they require a reachable HTTP endpoint, and third-party providers can't push to localhost. Here's how to build a reliable CI/CD testing strategy that actually catches webhook bugs before production.
Standard HMAC signatures verify payload integrity, but they don't authenticate the transport layer. Mutual TLS closes that gap — here's how to implement mTLS for webhook delivery when the stakes are high.
