Web API (Web Application Programming Interface) kya hai? Explained in simple Hindi

Web API (Web Application Programming Interface) ek aisa interface hai jo do systems ko ek doosre ke saath communicate karne ka tareeka deta hai, khas kar ek web server aur client ke beech. Web APIs ka istemal hum data exchange karne ke liye karte hain, jaise ki mobile apps, web applications, aur doosre software systems ko ek doosre se interact karne dena.

Web API ke kuch important features:

1. HTTP Protocol ka istemal – Web APIs HTTP requests ka istemal karti hain, jaise GET, POST, PUT, DELETE, taaki data ko retrieve ya modify kiya ja sake.
2. Stateless – Web APIs stateless hoti hain, iska matlab hai ki har request server ko independent hoti hai aur kisi pichhli request par depend nahi karti.
3. Format – Data ka format JSON (JavaScript Object Notation) ya XML mein hota hai, lekin zyadatar JSON format popular hai.

Example:

Agar aap kisi weather app ko check karte hain, toh wo weather information ke liye ek Web API se data request karta hai aur API weather server se data lekar app ko provide karta hai.
