Hi, The OperationAccessDenied.ACTION_NOT_PERMITTED error is encountered when you don't have the authorization to invoke the mutate method. It is possible that you're using the credentials with read-only access to create the user list. You will need to have either a standard or administrative access level to make changes to the advertiser's account. You could refer to the steps shown under "How to edit access level" section of this guide to edit the access level.
Feel free to write back if the error persists.
