Welcome to the REST API tutorial! This guide will walk you through the fundamentals of building and consuming RESTful APIs, using HTTP methods like GET, POST, PUT, and DELETE.

What is REST API?

REST (Representational State Transfer) is an architectural style for designing networked applications. It relies on a stateless, client-server communication protocol, typically using HTTP as the transport.

Key Concepts

  • Resources: Represented by URLs (e.g., /api/users).
  • HTTP Methods:
    • GET – Retrieve data ✅
    • POST – Create new data 🚀
    • PUT – Update existing data 🔄
    • DELETE – Remove data 📀
  • Status Codes: Understand 200, 404, 500, etc. 📊
