🐛 Troubleshooting

Common Issues

Authentication Errors

• Verify developer token is approved and active
• Check OAuth2 credentials are correctly configured
• Ensure customer ID format is correct (123-456-7890)
• For MCC: Verify manager account has access to selected managed account

Validation Errors

• Verify all required fields are provided
• Check date format: YYYY-MM-DD HH:MM:SS+TZ or use {{$now}}
• For enhanced conversions, provide at least one user identifier
• For MCC: Ensure managed account is selected when using manager account type

Rate Limiting

• Enable batch processing for high volumes
• Node automatically handles retries with exponential backoff
• Monitor Google Ads API quotas

Debug Information

Enable debug mode to see:

• Request payloads and headers
• Response data and status codes
• Retry attempts and delays
• Error details with stack traces
