Welcome to the API usage guide! This tutorial will help you understand how to interact with our HTTP server using API endpoints. Let's dive in!

What is an API? 📚

An API (Application Programming Interface) is a set of rules and protocols for building and integrating software applications. It allows different systems to communicate seamlessly. For example, when you make a request to /en/docs/tutorials/api_usage, you're using our API to access this documentation.

Key Concepts 🔍

  • Endpoints: Specific URLs where requests are sent, like /api/data or /api/users.
  • Methods: HTTP verbs such as GET, POST, PUT, and DELETE.
  • Headers: Metadata sent with requests, often containing authentication tokens.
  • Responses: Data returned by the server, typically in JSON format.

Example Request 📡

Here's a simple GET request to retrieve data: 

GET /api/data HTTP/1.1
Host: example.com
Accept: application/json
HTTP_Request

Best Practices ✅

  1. Always use GET for retrieving data.
  2. Include proper headers for authentication.
  3. Handle errors gracefully using status codes.
  4. Refer to our API Reference for detailed endpoint specifications.
