What is API Restfull?

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 define a set of constraints for how an API should behave, including using standard HTTP methods (GET, POST, PUT, DELETE) to perform operations on resources identified by URIs. They are commonly used for building web services, mobile applications, and integrating different systems due to their simplicity, scalability, and interoperability.
