Integration Guide

1

Review the API Documentation

Visit the official Auth0 documentation to understand available endpoints, request formats, and response structures. Familiarize yourself with the API's rate limits and usage policies before integration.

2

Obtain an API Key

Auth0 requires an API key for authentication. Register on the provider's website to get your unique key. Keep it secure and never expose it in client-side code — use environment variables or a backend proxy.

3

Use HTTPS for Secure Requests

Auth0 supports HTTPS, ensuring encrypted communication. Always use HTTPS endpoints in production to protect data in transit and comply with modern web security standards.

4

CORS Enabled — Direct Browser Access

Auth0 has CORS enabled, meaning you can make requests directly from the browser. This is ideal for frontend-only applications built with React, Vue, or vanilla JavaScript.

5

Implement and Test

Write your API integration code, start with a simple test request to verify connectivity. Implement proper error handling for network failures, rate limits, and invalid responses. Monitor your API usage to stay within any limits.

Code Examples

JavaScript / Fetch API:

javascript
// JavaScript example (with API key)
const apiKey = process.env.API_KEY; // Store your key securely

fetch("https://auth0.com", {
  headers: {
    "Authorization": `Bearer ${apiKey}`,
    // Or use: "X-API-Key": apiKey
    // Check the docs for the correct header format
  }
})
  .then(response => {
    if (!response.ok) {
      throw new Error(`HTTP error! status: ${response.status}`);
    }
    return response.json();
  })
  .then(data => {
    console.log("API response:", data);
  })
  .catch(error => {
    console.error("Error fetching from Auth0:", error);
  });

Python / Requests:

python
# Python example (with API key)
import requests
import os

api_key = os.environ.get("API_KEY")  # Store your key securely

headers = {
    "Authorization": f"Bearer {api_key}",
    # Or use: "X-API-Key": api_key
}

response = requests.get("https://auth0.com", headers=headers)

if response.status_code == 200:
    data = response.json()
    print("API response:", data)
else:
    print(f"Error: {response.status_code}")
