Best Practices

🔒 Security

  • ▸Always use HTTPS for API calls
  • ▸Store API keys in environment variables
  • ▸Implement request signing for server-to-server
  • ▸Validate HWID changes server-side
  • ▸Rate limit license validation calls

⚡ Performance

  • ▸Cache validation results locally
  • ▸Implement exponential backoff for retries
  • ▸Use async/await for non-blocking operations
  • ▸Batch license checks when possible
  • ▸Monitor API response times

✅ Testing

  • ▸Use test app IDs for development
  • ▸Mock license responses in unit tests
  • ▸Test HWID binding edge cases
  • ▸Validate error handling paths
  • ▸Run integration tests before deployment

🚀 Deployment

  • ▸Version your SDK integrations
  • ▸Plan for API deprecation warnings
  • ▸Monitor failed validations
  • ▸Keep error logs for debugging
  • ▸Have fallback authentication flows
