Getting all Accounts Information. Python API

[Fran Goitia]

I need to get all the accounts in my MCC. I basically need the name and ID. I'm using Python's API. I don't see how to do this in the docs and trying the example in account_management/"get_account_hierarchy.py" failed with:

suds.WebFault: Server raised fault: '[AuthenticationError.CLIENT_CUSTOMER_ID_IS_REQUIRED @ ; trigger:'<null>']'

I'm using v201705.

Hi Fran, 

This error occurs when the Client customer ID is not specified in the HTTP header. The clientCustomerId header is required for all calls to all services except CustomerService and ReportDefinitionService. You need to provide the AdWords Manager account Id in the "googleads.yaml" file and then retry the get_account_hierarchy.py example.
