Hi, Thank you for reaching out to the Google Ads API support team.
Please be informed that I have removed your response from the forums as it contains the PII information. Based on the information provided, I understand that you are trying to add a user interest ad group criteria to an existing ad group and encountering INVALID_USER_INTEREST error. When retrieving UserInterest to set in UserInterestInfo, verify the availabilities[] are compatible with the campaign type. Some UserInterest options are only available for specific campaign types. I would recommend you to refer to the “UserInterestInfo” documentation for more information. However, in order to further investigate your issue, kindly provide us with the complete API logs (request and response logs with request-id and request header) generated at your end to further assist you better. If you are using a client library and haven't enabled the logging yet, I would request you to enable logging for the specific client library that you are using. You can refer to the guides Java, .Net, PHP, Python, Ruby or Perl to enable logging at your end. For REST interface requests, you can enable logging via the curl command by using the -i flag. You can send the details via Reply privately to the author option, or direct private reply to this email. Thanks, Google Ads API Team Feedback How was our support today?
