RESTful APIs Complete Guide | HTTP Methods, Status Codes & Best Practices

A RESTful API design adheres to the principles of REST, using standard HTTP methods (GET, POST, PUT, DELETE) and stateless communication for efficient data exchange.

When handling errors in REST APIs, you should return appropriate HTTP status codes (e.g., 400 Bad Request, 500 Internal Server Error) and include detailed error information in the response body, such as an error code and a descriptive message.

When returning HTTP status codes, it's crucial to use them consistently to indicate the outcome of each request. For example, 200 OK signifies successful completion, while 404 Not Found indicates a missing resource.

A well-formatted error response should include fields such as an error code (for easy identification), a descriptive message explaining the issue, and a timestamp to track when the error occurred. It's best practice not to expose sensitive server details in these responses.
