Display & Video 360 API and SDF uploads that don't provide declarations will fail. See our deprecations page for more details on how to update your integration to make this declaration.
Required. The ID of the custom bidding algorithm that owns the rules resource.

Parameters
Union parameter owner. Required. Identifies the DV360 entity that owns the parent custom bidding algorithm. It can be either a partner or an advertiser. owner can be only one of the following:
