What is REST API?
REST (Representational State Transfer) API is an architectural style for designing networked applications. It provides a set of conventions for building web services that are scalable, maintainable, and easy to understand.
What REST API Does
REST APIs enable different systems to communicate over the internet using standard HTTP methods. They provide a way to access and manipulate resources (data) through a consistent interface, making it easier to build applications that work together.
How REST API Works
REST APIs follow these principles:
1. Stateless: Each request contains all necessary information
2. Client-Server: Clear separation between client and server
3. Cacheable: Responses can be cached for performance
4. Uniform Interface: Consistent way to interact with resources
5. Layered System: Can work through intermediaries
Common Uses
REST APIs are used in many applications:
Why It Matters
REST APIs are important because they:
HTTP Methods
REST APIs have become the standard for web service design, enabling the modern interconnected web of applications and services.
