Media Owners
Last Updated: February 16, 2026•

To best signal your video supply to buyers with STV budgets, you will need to pass the following required objects and attributes. For better monetization of your inventory, we strongly recommend that you pass as many attributes as possible to describe your inventory. We have included a list of recommended attributes that you can pass. For a complete list of supported attributes for each object, see List of supported OpenRTB bid request fields for sellers.
