Webhooks

Summary

A way for your server to notify another system in real time by sending an HTTP request when an event happens — the inverse of a normal API call, where the 'server' becomes the caller.

• 1Build an endpoint that receives a webhook from a third-party service (e.g. Stripe, GitHub).
• 2Verify webhook authenticity using a signature header, not just trusting the payload.
• 3Design your own webhook system that notifies external URLs when an event occurs in your app.
