What is RESTful API's?

RESTful APIs (Representational State Transfer) are an architectural style for designing networked applications. They rely on a stateless, client-server, cacheable communications protocol, and are often implemented using HTTP. RESTful APIs use standard HTTP methods (GET, POST, PUT, DELETE, etc.) to manage resources identified by URIs (Uniform Resource Identifiers). They are commonly used to build web services, mobile applications, and integrate different systems.
