Hi Stephen, Your code snippet looks fine to me. Here <https://github.com/googleads/googleads-python-lib/blob/master/examples/adwords/v201705/remarketing/add_crm_based_user_list.py> is a sample in our client library if you want to check. May be the user list id in your request is not a valid id in that account. Can you enable logging <https://github.com/googleads/googleads-python-lib#how-do-i-log-soap-interactions> and share the complete SOAP logs along with your client customer id with me?
