Hi, You can follow this guide <https://developers.google.com/adwords/api/docs/guides/authentication#webapp> to set up authentication for web application flow. If you would like to get the list of accounts that are directly accessible by a set of OAuth2 credentials, you need to use CustomerService.getCustomers() <https://developers.google.com/adwords/api/docs/reference/v201705/CustomerService#getcustomers> method without setting the clientCustomerId header. If you would like to get the list of accounts under a manager account, you need to use ManagedCustomerService.get() <https://developers.google.com/adwords/api/docs/reference/v201705/ManagedCustomerService#get> method as shown in the GetAccountHierarchy <https://github.com/googleads/googleads-java-lib/blob/master/examples/adwords_axis/src/main/java/adwords/axis/v201705/accountmanagement/GetAccountHierarchy.java> Java example. Example code in other languages is provided here <https://developers.google.com/adwords/api/docs/clientlibraries>.
