Webhooks are the simplest form of event-driven architecture — but applying the right patterns separates a brittle integration from a resilient system. Here are the architectural patterns that work at scale.
Naive rate limiting on webhook endpoints drops events permanently. Here's how to implement rate limiting that protects your infrastructure while ensuring every event is eventually delivered — with the right strategies for inbound and outbound flows.
Most webhook guides cover consuming webhooks. This one covers the other side — building the outbound webhook system that lets your customers subscribe to events happening in your platform.
The event schemas you ship today will need to evolve. Poor schema design creates breaking changes that knock out customer integrations. Here's how to design webhook payloads for long-term maintainability.
Webhook endpoints are HTTP endpoints with real-world consequences — a single vulnerability can lead to unauthorized charges, data exfiltration, or complete account takeover. Here's a security audit checklist for both inbound and outbound webhook infrastructure.
