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.

If containsEuPoliticalAds has been set to DOES_NOT_CONTAIN_EU_POLITICAL_ADVERTISING in the parent advertiser, then this field will be assigned DOES_NOT_CONTAIN_EU_POLITICAL_ADVERTISING if not otherwise specified. This field can then be updated using the UI, API, or Structured Data Files.
