Guides, comparisons, and deep dives on webhook infrastructure, reliability, and integration patterns.
Retries handle transient failures. But what happens when every retry is exhausted and a webhook still can't be delivered? Without a dead letter queue, that event is gone forever. Here's how to build one — or skip the work entirely.
Twilio signs every webhook with a scheme that's different from Stripe and GitHub — it includes the URL and sorted POST parameters. Here's how X-Twilio-Signature works and how to validate it correctly.
Signature verification is the single most common reason Stripe webhooks fail in production. Here's exactly how the Stripe-Signature header works, the four mistakes that break verification, and how to get it right.
After reviewing hundreds of webhook integrations, the same mistakes show up repeatedly. Here's a checklist of best practices covering signature verification, idempotency, async processing, and observability.
Slack's incoming webhook API is one of the simplest ways to send messages to a channel programmatically. Here's how to set it up, what the payload looks like, and how to send rich, formatted notifications.
Trigger.dev is a developer-friendly background jobs platform. Bluejay Relay is webhook-focused infrastructure. They're different tools for different jobs — here's the breakdown.
Inngest is a great tool for durable, multi-step background jobs. Bluejay Relay is built for webhook routing, transformation, and delivery reliability. Here's how to decide which one belongs in your stack.
Webhook schemas change. Fields get renamed, nested objects get restructured, new required fields appear. Without a versioning strategy, every schema change is a potential integration outage. Here's how to handle it.
Your webhook handler will receive the same event more than once. Network hiccups, retry logic, and race conditions make duplicates inevitable. Building an idempotent handler is how you stay sane.
Polling and webhooks both let your application react to changes in external systems. Choosing the wrong one costs you in latency, API quota, server load, or implementation complexity. Here's how to think about the trade-off.
A webhook is how services tell your application that something happened. Here's a plain-English explanation of what webhooks are, how they work, and when you'd use one instead of polling an API.
Testing webhooks is annoying because you can't just call a function — you need a running server with a public URL and a service willing to send you events. Here's every approach worth knowing.
