I wanna know about API

[RohitWaghire]

If you want to learn APIs, here’s an easy way to start:

First, understand what an API is by using existing APIs. There are many free public APIs online where you can practice sending requests and getting data back. This helps you understand how APIs work in real life.

Next, learn REST APIs, because they’re the most commonly used type. You don’t need to go deep at first—just understand how data is sent and received using URLs.

After that, try building a simple API yourself.
If you like JavaScript, use Node.js with Express.
If you prefer Python, use FastAPI or Flask.
Just make a small API that returns some sample data—nothing fancy.

Then, learn how to test APIs using tools like Postman. This teaches you how developers actually use APIs day to day.

Once you’re comfortable, you can look into API security basics (like login/authentication) and later explore GraphQL, which is another way of building APIs.

Best advice: don’t try to learn everything at once.
Use APIs → build a small one → test it → repeat.
