What is an API?

• API stands for Application Programming Interface.
• It allows two applications to communicate with each other.
• Example: When you use a food delivery app, it fetches restaurant data from a server using an API.

What is REST API?

• REST (Representational State Transfer) is an architectural style used for building web services.
• REST APIs allow communication between a client (e.g., a web browser, mobile app) and a server.
• It uses HTTP methods like GET, POST, PUT, DELETE to interact with data.

🔹Real-Life Example of REST API

• Think of a restaurant:
  • A customer (client) orders food from a waiter (API).
  • The waiter goes to the kitchen (server) and brings back the food.
  • The customer does not need to know how the kitchen works, they just request and receive.
  • Similarly, a REST API fetches data from a server when requested.
