Hi Joe, Yes, that's correct. Every API service such as CampaignService <https://developers.google.com/adwords/api/docs/reference/v201702/CampaignService> can only be executed on a per account basis and not for multiple accounts so you need to have separate API calls for every account you want to pull entities from such as campaigns.
The getAccountHierarchy sample code <https://github.com/googleads/googleads-python-lib/blob/master/examples/adwords/v201702/account_management/get_account_hierarchy.py> you referred to earlier for getting the list of clientCustomerId is a good starting reference for your development. After which, you can execute separate API calls for each clientCustomerId as you've mentioned. In addition, you may refer to this guide <https://developers.google.com/adwords/api/docs/guides/samples-use-cases#dsDropDownDefault> as reference for programmatically changing the clientCustomerId on runtime.
