Starting September 8, 2025, every new line item will need to declare whether or not they will serve Eurpoean Union (EU) political ads. 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 to fetch.
Query parameters
Parameters
Union parameter accessor. Required. Identifies which DV360 entity the request is being made within. The Get request will only return a custom bidding algortihm entity that is accessible to the DV360 entity identified within the accessor. accessor can be only one of the following:
