Webhook payloads change over time, and unlike REST APIs, there's no client library to absorb the difference. Here's how to version schemas, enforce backward compatibility, and prevent downstream breakage before it reaches production.
When a destination goes down, every upstream sender starts retrying simultaneously. Here's how retry storms form, why they extend outages, and the patterns that prevent them.
Blindly retrying every failed webhook delivery wastes resources and delays real alerts. A health scoring system lets you identify degraded destinations early, pause delivery automatically, and surface the right signal to your customers.
When your webhook gateway lives in us-east-1 and your customer's endpoint is in Tokyo, every delivery pays a 200ms tax. Here's how to architect regional forwarding to cut delivery latency without duplicating your entire infrastructure stack.
When a destination returns 429, your delivery engine needs to do more than retry — it needs to pause, back off per endpoint, and keep delivering to everyone else. Here's how to build per-destination throttling that doesn't stall your entire worker pool.
A well-designed event catalog lets developers discover, understand, and subscribe to webhook events without filing a support ticket. Here's how to structure one — from naming conventions to discovery APIs.
Most webhook failures start before your business logic ever runs. Understanding acknowledgment timeouts, async handoff patterns, and provider retry behavior is the foundation of a reliable webhook consumer.
Every major SaaS provider sends webhooks a little differently — different content types, batching strategies, and signature schemes. Here's what you actually need to know before you go to production with any of them.
Tunnels get you started, but they break in CI, require accounts, and route your dev traffic through third-party servers. Here's a more reliable approach to local webhook development using record-replay, local test harnesses, and injectable handler design.
Most webhook systems deliver events out of order by default. For most use cases that's fine — but for financial state machines, inventory systems, and audit logs, out-of-order delivery causes real bugs. Here's how to reason about ordering and enforce it when you need it.
When webhook delivery breaks, your customers feel it before you do. Here's how to build a public-facing status page that turns a support crisis into a self-service moment.
TLS protects webhooks in transit, but it doesn't protect them at rest inside a gateway, in logs, or at your destination. Here's how to add payload-level encryption when HTTPS alone isn't enough.
