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.
