  apiKey: 'xxx',
});

Deprecation Handling

Copy// Monitor for deprecation warnings in development
if (process.env.NODE_ENV === 'development') {
  process.on('warning', (warning) => {
    if (warning.name === 'DeprecationWarning') {
      console.warn('[Retell AI]', warning.message);
      // Log to tracking system for proactive updates
    }
  });
