Hi Martin,
Thanks for reaching out! There is currently no way to explicitly detect which campaigns are not following new policies unless you receive a
PolicyViolationError. There is no field in the
Campaign resource that will indicate any policy violations if you are looking to pull this information yourself. With that being said, there is also no way to update targeting of those campaigns automatically via API.
Let me know if you have additional questions.
Regards,
Danica, Google Ads API Team
