What are webhooks, and how can they be used in a RESTful API?

Short answer: Webhooks are server-to-server callbacks triggered by events. 👉 Example: Stripe API calls your endpoint /payment/confirmed when a payment succeeds.

Real-world example (ShopNest)

Creating an order is POST /api/orders → 201 with Location header. Fetching is GET /api/orders/{id} → 200 or 404.

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
