Webhooks

Webhooks are "user-defined HTTP callbacks". They are triggered by some event in a source system (e.g., Stripe, GitHub) and sent to a destination system (Your API) to notify it.

When to Use

• Payment Confirmations: Stripe notifying you a payment Succeeded.
• CI/CD: GitHub notifying Jenkins that code was pushed.
• Async Processing: A 3rd party AI service notifying you that generation is complete.

Quick Start

// Your Webhook Handler (Receiver)
app.post(
  "/webhooks/stripe",
  express.raw({ type: "application/json" }),
  (req, res) => {
    const signature = req.headers["stripe-signature"];
