Once you have the integration fully tested the following are the steps needed to transition from sandbox to production.

Security Best Practices

1. Never Expose Secrets:

   • ✅ Use environment variables for all sensitive data
   • ✅ Never commit secrets to version control
   • ✅ Use secret management services in production

2. HTTPS Only:

   • ✅ Always use HTTPS in production
   • ✅ Configure secure cookies
   • ✅ Use secure redirects

3. Token Security:

   • ✅ Store tokens securely (httpOnly cookies preferred)
   • ✅ Implement token refresh before expiration
   • ✅ Validate tokens server-side

4. API Security:

   • ✅ Use backend API endpoints for all sensitive operations
   • ✅ Implement rate limiting
   • ✅ Validate all inputs

Monitoring

Set up monitoring for:

• Authentication success/failure rates
• Token refresh failures
• Session creation failures
• API errors
• User experience metrics
