Hi,
Thank you for reaching out to our API support team.
Could you confirm if you are using the
AdWords API or the
Google Ads API? If you are using the AdWords API, you may only be able to modify your userslists since the REMOVE operator is not supported in the
AdwordsUserListService.mutate().
If you are using the Google Ads API, you may refer to this
document, specifically to this
section, on how you can manage your existing userlists.
Best regards,
