🎯 Advanced Usage

Filtering Errors

HealCode.init({
  token: 'your-token',
  beforeSend: (error) => {
    // Don't send errors from third-party scripts
    if (error.stacktrace?.includes('google-analytics')) {
      return null;
    }
    
    // Add custom data
    error.customData = {
      userId: getCurrentUserId(),
      feature: 'checkout'
    };
    
    return error;
  }
});

Manual Error Reporting

try {
  riskyOperation();
} catch (error) {
  HealCode.captureException(error, {
    level: 'error',
    tags: { feature: 'payment' }
  });
