: The client (the requester) and the server (the data provider) can evolve independently as long as the interface remains the same. The HTTP "Verbs" (Actions) How to Design a REST API and Why You Should - Websanova
: Resources are accessed via a consistent set of operations, keeping the system simple and decoupled.
: Every request from a client must contain all the information needed to understand and process it. The server does not store "session" context about the client.
To be truly "RESTful," a service must follow these foundational constraints :
: Data is identified by URIs (Uniform Resource Identifiers). For example, https://example.com identifies a specific user resource.
A is a lightweight, scalable architectural style that allows systems to communicate over the internet using standard HTTP protocols . Standing for REpresentational State Transfer , it treats every piece of data as a "resource" that can be manipulated through simple, universal actions. Core Principles
