📊 Implementation Examples

OAuth 2.0 Flow (Node.js)

const express = require('express');
const app = express();

app.get('/auth', (req, res) => {
  const authUrl = `https://accounts.google.com/oauth/authorize?` +
    `client_id=${CLIENT_ID}&` +
    `redirect_uri=${REDIRECT_URI}&` +
    `scope=openid email profile&` +
    `response_type=code`;
  
  res.redirect(authUrl);
});

app.get('/callback', async (req, res) => {
  const { code } = req.query;
  // Exchange code for tokens
  // Implement token validation
});
