Webhooks are a powerful way for apps to communicate in real time. Unlike APIs that require continuous polling for updates, webhooks automatically send data when an event occurs - making them efficient, instant, and easy to scale.
How Do Webhooks Work?
Every webhook follows the same three-step lifecycle:
- Event Triggered - An action occurs in the source system (e.g., a customer completes a payment).
- HTTP POST Sent - The source system sends an HTTP POST request containing the event data to a URL you registered.
- Your Server Responds - Your server receives the payload, processes it (update a database, send an email, trigger a workflow), and returns a
200 OK.
Why Use Webhooks?
- Instant Updates - Events arrive the moment they happen, with no polling delay.
- Efficient - Dramatically reduces unnecessary API calls and server load.
- Flexible - Works for payments, notifications, CI/CD pipelines, data sync, and more.
Example Use Case: Payment Confirmation
When a customer completes a purchase, Stripe or PayPal fires a webhook to your server carrying the transaction details. Your app can instantly update the order status, send a receipt, and provision access - all without the user waiting.
