Inventory Sources and Marketplace Connections

If you are a publisher with a VAST 3.0 compatible ad player, in the Inventory Source and Marketplace Connection setup workflows, you can select the VAST 3.0 response type (to support VAST 3.0 ad sources).

Inventory Source: Select VAST 3.0 Response Type in the Format Tab


Marketplace Connection: Select VAST 3.0 Response Type in the General Tab


VAST 3.0 is backwards compatible with VAST 1.x and VAST 2.0 creatives for both 1st and 3rd party served.

For additional information, see Inventory Sources, and Marketplace Connections articles.

Digital Ads

Within the Digital Ad General Tab, you can select your Ad Creative Type as 1st Party Served VAST 3.0 or 3rd Party Served VAST 3.0. The Ad will only serve / buy on inventory defined as VAST 3.0 compliant. Forecasting will correctly reflect potential inventory for VAST 3.0 Ads.
