Hi Adam, What I can recommend is for you to use the ManagedCustomerService <https://developers.google.com/adwords/api/docs/reference/v201708/ManagedCustomerService> and link all the other client accounts to an MCC <https://developers.google.com/adwords/api/docs/guides/accounts-overview#linking_accounts> that you own. Then, you can generate once again the OAuth2 credentials by carefully following this guide <https://developers.google.com/adwords/api/docs/guides/authentication>. This should allow you to manage information on the clients belonging to your hierarchy. Let me know if this works for you.
