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.

The advertisers to add or remove from the list of advertisers that have read/write access to the inventory source. This change will remove an existing partner read/write accessor.
