Hi, Thank you for reaching out to the Google Ads API support team.
Kindly note that currently there is no resource or field in the Google Ads API to retrieve the user_list.size_for_youtube or user_list.size_for_gmail via the Google Ads API. As this feature is available in the UI, I will raise a feature request to access user_list.size_for_youtube or user_list.size_for_gmail data via the Google Ads API. However, I cannot provide a scheduled timeline for its availability. I would recommend monitoring our Blog Post and Release Notes for updates regarding future changes. Regarding customer lists via the API: Account owners or administrators can use the Google Ads API to upload data files and manage Customer Match segments. Advertisers can upload a data file, add or remove customer data, or edit configurations through the API. For more information, visit the data section of the Google Ads API documentation. OfflineUserDataJobService and UserDataService are the services used for uploading customer match list data. Please refer to the suggested documentation for step-by-step guidance on how to programmatically manage customer match lists via the API. Thanks, Google Ads API Team Feedback How was our support today?
