Hi Tiana, The CustomerService.getCustomers <https://developers.google.com/adwords/api/docs/reference/v201609/CustomerService#getcustomers> method returns only the details of the specified account in the *clientCustomerId* field of the request header. Additionally, the client library has the GetAccountHierarchy <https://developers.google.com/adwords/api/docs/samples/java/account-management#get-the-account-hierarchy-under-the-current-account> (other languages also available in the link) example wherein it uses the ManagedCustomerService <https://developers.google.com/adwords/api/docs/reference/v201609/ManagedCustomerService> to fetch the full list of accounts under an MCC account by specifying the MCC account ID in the clientCustomerId field. It cannot, however, fetch information vice-versa wherein you will fetch all the connected MCCs of a given customer account.
