Learn about API mocking, mock servers, and best practices for testing and development
State Machines in API Mocking
Most mock servers return the same response every time you hit an endpoint. But real APIs don't work that way. An order starts as "pending," becomes "confirmed," then "shipped," and finally "delivered." A payment goes from "processing" to either "success" or "failed." A user registration flow moves t

Unlike HTTP, where the client must initiate every request, WebSockets allow both sides to send messages at any time. Think of HTTP as sending letters back and forth - you write, send, w

You're building an e-commerce app. A customer completes a payment, and you need to update their order status, send a confirmation email, and notify the warehouse. How does your payment provider tell your app that the payment succeeded? This is exactly where webhooks come in. What is a Webhook? A web

Your API works perfectly in development. You've tested it manually, the endpoints return the right data, and everything looks good. Then you deploy to production, and suddenly your mobile app crashes because of an unexpected null value, your frontend freezes waiting for a slow response, and your err

Your API returns the correct data. Your tests pass. Everything works perfectly—until it doesn't. Users start complaining that the app feels slow. Pages take forever to load. Buttons don't respond. The API is working, but it's working slowly. This is the latency problem, and it's one of the most comm
