🧠 What is an API?
API (Application Programming Interface) is a set of rules and protocols that allows one software application to communicate with another. It acts as a bridge between two systems, enabling them to share data and perform operations seamlessly.
📱 Simple Example:
Think of an API like a waiter in a restaurant:
- You (the client) place an order.
- The waiter (API) takes your order to the kitchen (server).
- The kitchen prepares your food and sends it back through the waiter.
Similarly, an API takes a request from one application, gets the data from another system, and returns it to you.
🔍 Where is API Used?
APIs are everywhere in the digital world. Here are some of the most common use cases:
1. Mobile Applications
APIs connect your mobile apps to services:
- Example: Food delivery apps use APIs to fetch restaurant data, track orders, and process payments.
2. Web Applications
Web apps use APIs to pull data dynamically.
- Example: Travel booking sites use APIs to collect prices from multiple airlines or hotels.
3. Social Media Integration
APIs let websites connect to platforms like Facebook, Instagram, or LinkedIn.
- Example: “Login with Google” or “Share on Twitter” uses their APIs.
4. Payment Gateways
APIs power secure payment processing.
- Example: Razorpay, PayPal, and Stripe APIs handle online transactions.
5. IoT Devices
Smart devices use APIs to communicate and operate.
- Example: A smart thermostat adjusting your temperature via mobile app.
6. Machine Learning & AI
APIs provide access to trained AI models or ML tools.
- Example: Google Vision API or ChatGPT API processes user inputs and returns intelligent responses.
