Understand webhooks like Stripe engineers do.

Hey Product Hunt! 👋

We just published a deep dive into one of the most deceptively tricky parts of modern developer infrastructure: webhooks.

They seem simple at first — just an HTTP POST when something happens — but once you start handling retries, idempotency, queuing, DLQs, signature verification, and observability, it quickly turns into a full-blown system on its own.

This post breaks down:

• What webhooks actually are (beyond just a buzzword)

• How they work under the hood — request structure, security, delivery guarantees

• The challenges teams face when they scale webhook traffic

• Best practices for building reliable webhook-based integrations

• Real-world examples from companies like Stripe, GitHub, and Shopify

We're building Vartiq, a webhook infrastructure platform to solve these exact challenges — so if you’ve ever had to babysit failing webhooks or build retry queues from scratch, this might be useful.

Would love to hear your thoughts, horror stories, or battle-tested webhook lessons!
