REST (Representational State Transfer) is an architectural style used for designing web services that communicate over the internet. It enables applications to exchange data in a simple, scalable, and flexible manner using standard HTTP protocols.

Today, REST is the most widely used architecture for building APIs in modern applications, including web, mobile, and cloud-based services.

In this article, we will explore:

✔ What REST is and why it matters
✔ Key principles of REST architecture
✔ HTTP methods used in RESTful APIs
✔ Real-world examples and use cases

Let’s get started! 🚀

🔹 What is REST?

REST (Representational State Transfer) is a set of architectural principles for designing networked applications. It was introduced by Roy Fielding in 2000 as part of his doctoral dissertation.

In simple terms, REST provides a way for computers to talk to each other over the internet in a stateless and scalable manner using HTTP requests.
