API Guide – Knowledge Base

Introduction

Welcome to the API Guide. This document provides a comprehensive walkthrough of our RESTful API, covering authentication, request structure, response formats, error handling, and best practices.

Authentication

All API requests must include a valid Bearer Token in the Authorization header.

Authorization: Bearer YOUR_ACCESS_TOKEN

Obtain your token from the Authentication Guide.

Endpoints Overview

Method	Endpoint	Description
GET	/api/v1/users	List all users
POST	/api/v1/users	Create a new user
GET	/api/v1/users/{id}	Retrieve a specific user
PUT	/api/v1/users/{id}	Update a user
DELETE	/api/v1/users/{id}	Delete a user

Example Request

Fetching a list of users using fetch in JavaScript:

fetch('https://api.example.com/api/v1/users', {
    method: 'GET',
    headers: {
        'Authorization': 'Bearer YOUR_ACCESS_TOKEN',
        'Content-Type': 'application/json'
    }
})
.then(response => response.json())
.then(data => console.log(data))
.catch(err => console.error('Error:', err));

Error Handling

The API returns standard HTTP status codes. Common responses:

400 Bad Request – Invalid request payload.
401 Unauthorized – Missing or invalid token.
403 Forbidden – Insufficient permissions.
404 Not Found – Resource does not exist.
429 Too Many Requests – Rate limit exceeded.
500 Internal Server Error – Unexpected server error.

Rate Limiting

Each token is limited to 120 requests per minute. Exceeding this limit returns a 429 status with a Retry-After header.
