HTTP status codes are standardized three-digit response codes that a server returns to indicate the result of processing a client’s request. These codes play a crucial role in HTTP-based communication for web browsers, API clients, and search engines by showing whether a request succeeds, requires redirection, or fails with a client-side or server-side error. In RESTful API design, choosing the right status codes has a major impact on API clarity and developer experience. ...
