What is API's REST?

REST (Representational State Transfer) is an architectural style for designing networked applications. It relies on a stateless, client-server communication protocol, typically HTTP. REST APIs define a set of rules that developers follow when creating and interacting with web services. Key principles include using standard HTTP methods (GET, POST, PUT, DELETE) to perform operations on resources, identifying resources using URLs, and representing resources in formats like JSON or XML. REST APIs are widely used for building web applications, mobile apps, and integrating different systems.
