Starting March 25, 2021, we are rolling out a change in the Google Ads API and AdWords API, to require advertisers who apply to the latest Personalized advertising policies to acknowledge these changes in the Google Ads UI. Campaign creation requests via the API will be rejected for these advertisers until they click to accept the changes.

Who will be impacted?
Advertisers promoting housing, employment, or credit products or services to audiences in the U.S. and Canada will be impacted.

What's changing?
You will receive the following errors when trying to create new campaigns via the API if the new policies have not been acknowledge:

API Version	Error Code	Error Message
Google Ads API v6.1	CampaignError.HEC_AGREEMENT_REQUIRED	Customers with Housing, Employment, or Credit ads must accept updated personalized ads policy to continue creating campaigns
Google Ads API (older versions)	CampaignError.UNKNOWN	Same as above.
AdWords API (v201809)	CampaignService.OperationAccessDenied	Same as above.

What should you do?

• Before March 25, 2021, make sure to add support for the new policy errors in your application.
• Ensure that the account administrators have accepted the policy changes in the Google Ads UI following this guide.

If you have any questions or need additional help, contact us through the Google Ads API and AdWords API forum or at [email protected].
