What is RESTfull API?

RESTful APIs (Representational State Transfer) are an architectural style for designing networked applications. They rely on a stateless, client-server communication protocol, typically HTTP. RESTful APIs use standard HTTP methods (GET, POST, PUT, DELETE) to perform operations on resources, which are identified by URLs. They are commonly used to build web services, mobile applications, and integrate different systems by providing a standardized way to access and manipulate data.
