CMP - Downstream Demand Partners

If your CMP provides an option to automatically disclose all registered IAB vendor IDs, we strongly recommend enabling that setting. 

If you cannot enable automatic vendor disclosure in your CMP, please do the following: 

1. Enable Underdog Media and all downstream demand as approved vendors in your CMP - 

Vendor Name	Vendor ID
