Representational State Transfer (REST)

Representational State Transfer (REST) is an architectural style for designing networked applications. It relies on a stateless, client-server communication protocol—almost always HTTP—and is the standard for building APIs that are scalable, maintainable, and lightweight.

In a RESTful system, everything is considered a Resource (such as a user, an order, or a product), each identified by a unique URL (URI). Developers interact with these resources using standard HTTP verbs: GET (read), POST (create), PUT (update), and DELETE (remove). A key principle of REST is that it is Stateless, meaning each request from the client must contain all the information necessary for the server to understand and process it; the server does not store “session” context between requests.

The Six Constraints of REST

To be truly RESTful, an API must follow six constraints: Client-Server separation, Statelessness, Cacheability, a Uniform Interface, a Layered System, and (optionally) Code on Demand. The Uniform Interface is the most famous, requiring that resources are identified in requests and manipulated through representations (usually JSON).

While REST is technically independent of data formats, JSON (JavaScript Object Notation) has become the industry standard for RESTful APIs. It is lightweight, easy for humans to read, and natively supported by almost every modern programming language, making it ideal for data exchange between a frontend SPA and a backend server.

SOAP (Simple Object Access Protocol) is a strict, XML-based protocol with heavy specifications. REST is an architectural style that is much more flexible, utilizes standard HTTP, and is generally faster and more efficient for web and mobile applications.

RESTful services use standard HTTP codes to communicate the result of a request. For example, 200 OK indicates success, 201 Created confirms a new resource was made, 400 Bad Request points to a client error, and 404 Not Found indicates the resource does not exist.
