Zunoy MockAPI is mainly useful for teams that need APIs for development or testing before the real backend is ready. Instead of waiting for the actual API, users can create mock endpoints and use them in their frontend work, QA testing, or internal demos. It lets users define responses, status codes, headers, query params, auth, and other request details based on what they want to test. Different scenarios can also be added for the same endpoint, so it becomes easier to check how an app behaves in different cases. For example, a team can test success and error responses without changing the real API. Another useful part is that Zunoy MockAPI also gives API docs and request logs, so teams can see how the mock APIs are being used and share the details easily with others. Overall, it helps reduce waiting time during development and makes it easier for frontend and testing work to continue even if backend APIs are not available yet.
