Chapter 9. RESTful APIs

Representational State Transfer (REST) is a modern approach for client-server communications that decouple the client (such as Bowers and mobile applications) from the server components in applications. RESTful implementations enable backend implementations to speak a common language (usually, XML or JSON) while taking complete advantage of HTTP verbs, such as GET, POST, PUT, and DELETE. RESTful applications enable us to build stateless, scalable, and uniform applications that we can distribute to our clients. With Yii2, we can quickly implement RESTful APIs as either a part or the whole of our application.
