Frequently asked questions

How do I simulate API errors?

Set the status code to 400, 401, 403, 404, or 500 to test how your frontend handles different error scenarios. Add appropriate error messages in the response body.

Can I add response delays?

Yes! Set a delay in milliseconds to simulate slow API responses. This helps test loading states and timeout handling in your application.

How long do mock endpoints last?

Mock endpoints remain active for 24 hours. They're perfect for development and testing but shouldn't be used for production workloads.
