SDK Generation Process

Developer Integration Example

// JavaScript/TypeScript SDK Example
import { LoginHealth } from '@login-health/sdk';

// Initialize client
const client = new LoginHealth({
  clientId: 'YOUR_CLIENT_ID',
  redirectUri: 'https://your-app.com/callback'
});

// Authentication flow
async function login() {
  // Redirect to Login.Health authentication
  await client.auth.login({
    scopes: ['user:read', 'records:read']
  });
}

// Handle callback and retrieve data
async function handleCallback(code) {
  // Exchange code for tokens
  await client.auth.exchangeCodeForToken(code);

  // Get user profile
  const user = await client.users.getCurrentUser();

  // Get health records
  const records = await client.records.getRecords({
    category: 'medication',
    status: 'active'
  });

  // Access data
  console.log(`Found ${records.length} medications for ${user.firstName}`);
}
