A REST API (Representational State Transfer Application Programming Interface) is a set of rules that allows different software systems to communicate over the internet using HTTP requests.
🌐 Key Concepts:
Stateless: Each API call is independent, and the server doesn’t store client data between requests.
HTTP Methods: Uses standard methods like:
GET: Retrieve data
POST: Submit new data
PUT: Update existing data
DELETE: Remove data
Resource-Based: Resources (like users, posts, or products) are represented by URLs, and the actions on these resources are performed using HTTP methods.
🔗 Why Use REST API?
Simple: Easy to understand and implement.
Scalable: Ideal for handling multiple clients (e.g., mobile, web apps).
Flexible: Works with different formats like JSON, XML.
