MCC sub accounts creation error AuthenticationError.CLIENT_CUSTOMER_ID_IS_REQUIRED

[g...@alpha9marketing.com]

Look the yaml file:

adwords:

  client_id: 'MYCLIENTID.apps.googleusercontent.com'

  client_secret: 'HIDDEN SECRET'

  refresh_token: 'MY REFRESH TOKEN'

  user_agent: 'My UA'

  developer_token: 'MY DEV TOKEN'

I am using python (https://github.com/googleads/googleads-python-lib).

I used to be able to create sub accounts (python code):

YAML_KEY = 'adwords'

# A list of values which must be provided to use AdWords.

REQUIRED_INIT_VALUES = ('user_agent', 'developer_token')

# A list of values which may optionally be provided when using AdWords.

OPTIONAL_INIT_VALUES = ('validate_only', 'partial_failure', 'client_customer_id', 'https_proxy')

yaml_path = '/home/kk/googleads.yaml'

kwargs = googleads.common.LoadFromStorage(

                    yaml_path, YAML_KEY, REQUIRED_INIT_VALUES,

                    OPTIONAL_INIT_VALUES)

client = adwords.AdWordsClient(**kwargs)

import random

rnum = random.randint(1, 10000)
acc_name = 'Test client %d' % rnum
currency, timezone = 'EUR', 'Europe/Berlin'
operations = [{

            'operator': 'ADD',

            'operand': {

              'name': acc_name,

              'currencyCode': currency,

              'dateTimeZone': timezone,

            }

        }]

managed_customer_service = client.GetService(

            'ManagedCustomerService', version='v201409')

accounts = managed_customer_service.mutate(operations)

I am getting the error:
WebFault: Server raised fault: '[AuthenticationError.CLIENT_CUSTOMER_ID_IS_REQUIRED @ ; trigger:'<null>']'

I am pretty sure the code above was working . In fact I have already created some accounts

Thanks

The Test MCC account allows only 9 test sub accounts to be created.

That was the problem.

In my message above I wrote:

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

This errors happened because I did not include the MCC's customer id in the request.

Hi,

Glad you were able to resolve this. Note that starting with v201409 you need to include the clientCustomerId SOAP header for all services except CustomerService (see the v201409 migration guide).

Cheers,
