Topics API

Topics API is part of Privacy Sandbox proposed by Google Chrome and providing third party callers on the web page with advertising topics that might interest the current visitor of the page. These topics supplement the contextual information about the page and support interest-based advertising that doesn’t rely on third party cookies.

Topics are passed to Buyers in the user.data.ext.segtax field which specifies the taxonomy being used, as per Approved Vendor Specific Taxonomies. The field value is equal to 60x; at this moment 600 represents Topics v1, 601 represents Topics v2, 602+ are reserved for future versions. See the Ext Object section for details.
