AuthenticationError.CLIENT_CUSTOMER_ID_IS_REQUIRED on MCC sub account for examples

[tic...@onmacon.de]

Hi,

I´m using Python. I finally managed to get the access thing running (in fact I hope so). I filled in the values into my googleads.yaml at the "adwords:" section. The file is saved in my home path so that adwords.AdWordsClient.LoadFromStorage() should load this file.

Now I figured out that some offical examples don´t work for me. Instead they throw a "suds.WebFault: Server raised fault: '[AuthenticationError.CLIENT_CUSTOMER_ID_IS_REQUIRED @ ; trigger:'<null>']'" at me.

e.g. calling v201409/basic_operations/get_text_ads.py throws:

No handlers could be found for logger "suds.client"
Traceback (most recent call last):
  File "./get_text_ads.py", line 85, in <module>
    main(adwords_client, AD_GROUP_ID)
  File "./get_text_ads.py", line 67, in main
    page = ad_group_ad_service.get(selector)
  File "/usr/local/lib/python2.7/dist-packages/googleads/common.py", line 264, in MakeSoapRequest
    for arg in args])

  File "build/bdist.linux-x86_64/egg/suds/client.py", line 602, in invoke

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

When I´m telling pip to upgrade googleads it tells me that it´s "already up-to-date". So this shouldn´t be an old version issue.

I´ve read https://groups.google.com/forum/#!topic/adwords-api/w1bBf0lFmPY but I don´t know how I am able "to include the clientCustomerId SOAP header". Besides, is it really necessary to fix the example sources?! I think I´m missing something essential but i have no clue.

Kind regards

Hi,

You can set clientCustomerId either in your googleads.yaml file (https://github.com/googleads/googleads-python-lib/blob/master/googleads.yaml#L8), or you can set this at the runtime (https://github.com/googleads/googleads-python-lib/blob/master/README.md#how-do-i-change-the-client-customer-id-at-runtime). If you want to retrieve your client customer ids under an MCC at runtime, see https://github.com/googleads/googleads-python-lib/blob/master/examples/adwords/v201409/account_management/get_account_hierarchy.py.

Thank you for the quick response!
Turns out I confused clientId with customClientId. Now it works for me.
