Request Body

A request body is the data sent by a client to a server as part of an HTTP request, typically used in methods like POST, PUT, or PATCH to create or update resources. It contains structured information such as JSON, XML, or form data that the server processes to perform operations. This concept is fundamental in web development for handling user input, API interactions, and data transmission between systems.

Also known as: HTTP Request Body, Request Payload, Body Data, Request Data, Req Body

Why learn Request Body?

Developers should learn about request bodies when building web applications, APIs, or services that require client-server data exchange, such as form submissions, RESTful API endpoints, or file uploads. It is essential for handling user authentication, data validation, and ensuring secure and efficient communication in modern web and mobile development.
