Hi Edward, The case of having no link between accounts is applicable for same environment accounts only and there is no way to create a link between test and production accounts. This said, if your production client account is not linked to the production MCC account where your developer token is associated to, then this error will occur. The same applies for test MCC accounts and test client accounts.
One way to check if the accounts are linked is by using the GetAccountHierarchy <https://developers.google.com/adwords/api/docs/samples/java/account-management#get-the-account-hierarchy-under-the-current-account> example. Please make sure to specify the test or production MCC account id in the *client_customer_id* field of your *adwords_api.yml* when you run the example to see which client accounts are linked to it. Additionally, for linking accounts, please carefully follow this guide <https://developers.google.com/adwords/api/docs/guides/accounts-overview#linking_accounts> as to how.
