What is RESTful APIs?

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 widely used for building web services, mobile apps, and integrating different systems because of their simplicity, scalability, and flexibility.
