Join us live on Discord on the Google Advertising and Measurement Community server and on YouTube on February 26th at 10:00 AM EST! We will discuss the new features added in v23.1 of the Google Ads API.

Support for European Union Political Ads Regulation

In October 2025, Google stopped serving political advertising in the European Union ahead of a new political ads regulation. This guide summarizes the support for the EU Political Ads Regulation in the Google Ads API.

Support for self-declaration of EU political ads

Google Ads API supports self-declaring a campaign for EU political ads using the contains_eu_political_advertising field. The possible values and their meaning are shown in the following table.

Value	Meaning
`CONTAINS_EU_POLITICAL_ADVERTISING`	The campaign has EU political ads.
`DOES_NOT_CONTAIN_EU_POLITICAL_ADVERTISING`	The campaign does not have EU political ads.
`UNSPECIFIED`	The campaign is missing self-declaration about EU political ads.

You can retrieve the self-declaration status of a campaign in Google Ads API by running the following query using either the Search or SearchStream methods of the GoogleAdsService.

select campaign.id, campaign.contains_eu_political_advertising from campaign

Campaign-level API validation and enforcement

All new campaigns created through the Google Ads API should set the contains_eu_political_advertising field. The API call to create a new campaign using CampaignService.MutateCampaigns will fail with a FieldError.REQUIRED error if this field is not set.

All the existing campaigns should set the contains_eu_political_advertising field before attempting to change proximity, location, or location_group targeting either at the campaign or ad group levels. The API call to create or update these campaign criteria using the CampaignCriterionService.MutateCampaignCriteria method for existing campaigns will fail with a CriterionError.MISSING_EU_POLITICAL_ADVERTISING_SELF_DECLARATION error if the campaign hasn't completed the self-declaration. The API call to create or update these ad group criteria using the AdGroupCriterionService.MutateAdGroupCriteria method will also fail in a similar manner if the campaign hasn't completed the self-declaration.

These enforcements also apply to other mechanisms that you can use to make campaigns, such as running Batch Jobs and using GoogleAdsService.Mutate method to create and update entities. Attempting to schedule a new experiment using the ExperimentService.ScheduleExperiment method will throw an ExperimentError.MISSING_EU_POLITICAL_ADVERTISING_SELF_DECLARATION error if the contains_eu_political_advertising declaration is missing on the treatment draft campaigns.

Account-level API validation and enforcement changes

Starting on April 1, 2026, if a Google Ads account has one or more undeclared campaigns, the Google Ads API will fail all mutate calls related to campaign management with a MutateError.EU_POLITICAL_ADVERTISING_DECLARATION_REQUIRED error. All other calls--such as reporting, account management or keyword planner--will continue to work unaffected. See the full list of methods.

How to declare existing undeclared campaigns

To declare existing undeclared campaigns, retrieve the list of eligible campaigns, and set their contains_eu_political_advertising declaration using the CampaignService.MutateCampaigns method, the GoogleAdsService.Mutate method, or using the BatchJobService. These methods won't fail with a MutateError.EU_POLITICAL_ADVERTISING_DECLARATION_REQUIRED error as long as you only update the campaign's contains_eu_political_advertising field.

You can retrieve the list of undeclared campaigns by running the following GAQL query using either the Search or SearchStream methods of the GoogleAdsService.

select campaign.id
  from
    campaign
  where
    campaign.missing_eu_political_advertising_declaration = true

You can also declare undeclared campaigns on the Google Ads account level using the Google Ads UI. The account level declaration status can be retrieved using the contains_eu_political_advertising field of the Customer object.

Effect on campaign serving

Any campaign that has declared EU political ads by setting contains_eu_political_advertising to true will stop serving ads in the EU. Learn more.

Existing campaigns without a declaration will remain unaffected for now.
