What is RESTful API design?

RESTful API design is an architectural style for building networked applications. It relies 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 for web services, mobile applications, and integrating different systems due to their simplicity, scalability, and interoperability.
