Bidders - Category service

Article
01/16/2025

The read-only Category Service allows you to view all categories that are registered in the Xandr system. Categories are assigned to both brands and creatives - you can see what categories are assigned using the Brand Service or the Creative Service. You can then allow or disallow these categories of brands and creatives using the Ad Profile Service.

Note

For site and placement categories, use the Content Category Service.
