Welcome to the API Basics guide! This document will walk you through the fundamentals of working with APIs, including key concepts and best practices.

What is an API?

An API (Application Programming Interface) is a set of rules and protocols for building and integrating software applications. 🌐
It enables different systems to communicate and share data seamlessly.

Key Components of an API

  • Endpoints: Specific URLs where data is requested or sent.
  • Methods: HTTP verbs like GET, POST, PUT, DELETE.
  • Request/Response: Data exchanged between client and server.

How to Use an API

  1. Identify the Endpoint
    Example: GET /users to retrieve user data.

  2. Choose the Method
    Use GET for retrieving data, POST for creating new resources.

  3. Send a Request
    Include headers and body as needed.
    📌 Learn more about HTTP requests

  4. Handle the Response
    Parse JSON or XML responses to extract data.

Best Practices

  • Always validate input data before processing.
  • Use proper error handling for failed requests.
  • Document your API thoroughly for clarity.
