Overview

ReqRes is a free, hosted fake REST API designed for testing and prototyping front-end applications. It returns realistic user and resource data without any authentication, making it ideal for beginners learning how to work with APIs. Use it to test login flows, pagination, and CRUD operations before connecting a real backend.

💡

Beginner Tip

ReqRes is one of the best learning tools for beginners—it supports GET, POST, PUT, PATCH, and DELETE with no setup required. Try creating a user with a POST request to see how the server returns the newly created resource with an ID.

Common Errors & Troubleshooting

404 Not Found Accessing a user ID that does not exist (e.g., /api/users/100)
✓ Use valid user IDs (1-12). ReqRes only has a limited set of fake users.
Empty response body on POST Sending a POST without a Content-Type header
✓ Add -H "Content-Type: application/json" and send a JSON body with -d '{"name":"test"}'.
422 Unprocessable Entity on /register Missing the password field in the registration payload
✓ Include both email and password fields. Use one of the predefined emails like "[email protected]".
