🙌 Namaskara! Welcome to Tech with Rajesh! 🚀

Happy to share this post with you! Spend just 4 minutes and 07 seconds, and you’ll learn about API integration in the simplest way. Let’s dive in!

1️⃣ What is an API?
API (Application Programming Interface) is a messenger between two applications. It allows them to talk and exchange data without knowing each other’s internal details.

2️⃣ Why is an API needed?
APIs help different systems communicate efficiently. Without APIs, every application would have to build its own way to fetch and share data, which is time-consuming and inefficient.

3️⃣ What are the basic things in an API?

  • Request → The data you ask for.
  • Response → The data you get back.
  • Endpoint → The URL where the API is available.
  • Methods (HTTP verbs) → Like GET (to fetch data), POST (to send data), PUT (to update data), and DELETE (to remove data).
  • Authentication → Ensuring only the right users can access the API.

4️⃣ How does an API work?

  1. You (User) send a request.
  2. API takes your request and sends it to the right system.
  3. The system processes the request and sends a response.
  4. API delivers the response back to you.

🏏 Real-World Example: IPL Live Scores API 🏏
Imagine you want to check live IPL scores in a cricket app. That app doesn’t store the scores—it fetches them using an API from the official cricket board.

1️⃣ You open the app and tap "Live Scores."
2️⃣ The app sends a request to the IPL API.
3️⃣ The IPL API fetches real-time match data from its database.
4️⃣ The API sends the response (live scores) back to the app.
5️⃣ The app displays the scores on your screen.

This is how APIs make things fast, real-time, and efficient! 🚀

5.Which programming language is used to write an API?

APIs can be written in any programming language that supports web communication. Popular languages include:

  • Node.js (JavaScript) – Fast and widely used.
  • Python (Flask/Django) – Simple and powerful.
  • Java (Spring Boot) – Secure and scalable.
  • PHP (Laravel) – Good for web applications.
  • C# (.NET) – Used in enterprise apps.

6.If a request is made, which language is required & how does it request data?

  • The client (frontend or another system) makes a request using HTTP (HyperText Transfer Protocol).
  • The request can be made from JavaScript (Fetch API, Axios), Python (Requests), Postman, or Curl.

Example request in JavaScript using Fetch API:

fetch('https://api.example.com/ipl-scores')
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error('Error:', error));

7. In which format is the response received?
APIs usually return data in JSON (JavaScript Object Notation) format because it is lightweight and easy to read.

Sometimes, APIs may return XML (Extensible Markup Language), but JSON is more common.

Example JSON response:

{
  "match": "RCB vs CSK",
  "score": "RCB 180/4 in 18.3 overs",
  "status": "Live"
}

This response can be used in web apps, mobile apps, or dashboards to display data dynamically. 🚀
