About REST API Mocker

The REST API Mocker is a high-productivity tool designed to keep development teams moving forward without waiting for backend services. This tool allows frontend developers to define expected API responses, specify status codes, and simulate various scenarios (success, error, latency) in seconds. By creating temporary endpoints that behave like real services, teams can build, test, and integrate UI components against semi-realistic data long before the production logic is written. It's the perfect solution for agile development, rapid prototyping, and bug reproduction.

How to Use REST API Mocker

1. Select the HTTP method (GET, POST, PUT, DELETE) for your mock endpoint
2. Enter the desired JSON response body in the editor provided
3. Configure the HTTP status code (e.g., 200 OK, 404 Not Found, 500 Error)
4. Specify an optional delay to simulate real-world networking conditions
5. Click 'Generate Endpoint' to create your temporary mock URL
6. Copy the generated URL and use it in your frontend code (Fetch, Axios, etc.)
7. Interact with the endpoint like a real service to see your data returned
8. Manage and update your active mocks directly from the dashboard
