Hi, Thanks for reaching out to us.
Could you confirm if you are trying to set selective optimization on a search or display campaign? If so, I don't believe that should work. Note that Selective optimization is only supposed to be used with App campaigns in the API as shown here: https://developers.google.com/adwords/api/docs/guides/mobile-app-campaigns. Also, please note that the AdWords API is deprecated and will be sunset on April 27, 2022. We strongly recommend that you migrate to the Google Ads API as soon as possible. Let us know if you have any further questions. Regards, Reminder: Share your feedback about the Google Ads (AdWords) API!
