HTTP

HTTP status codes are standardized three-digit numeric response codes that a server returns to indicate the result of processing a client’s request. These codes play a crucial role in all HTTP-based communications including web browsers, API clients, and search engines, clearly conveying whether requests succeeded, require redirection, or encountered client or server-side errors. In RESTful API design, selecting appropriate status codes is a key factor that significantly impacts API intuitiveness and developer experience. ...

HTTP (HyperText Transfer Protocol) methods are core elements of client-server communication protocols that have continuously evolved since Tim Berners-Lee first introduced them when designing the World Wide Web in 1991. The HTTP/1.1 standard (RFC 7231) defines 9 standard methods: GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS, CONNECT, and TRACE. Each method has important characteristics of idempotency and safety, playing essential roles in RESTful API design and web application development.
