API not allow me to get all MMC client list

[Michal Kubek]

I'm trying to get list of all accounts im MMC account.

For that reason I try to use all versions of https://github.com/googleads/googleads-python-lib/blob/master/examples/adwords/v201708/account_management/get_account_hierarchy.py

But all version of AdWords api are returning 

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

or full stack 

python get_account_hierarchy.py
No handlers could be found for logger "suds.client"
WebFault(u"Server raised fault: '[AuthenticationError.CLIENT_CUSTOMER_ID_IS_REQUIRED @ ; trigger:'<null>']'",)

When i specified  CUSTOMER_ID I can download ACCOUNT_PERFORMANCE_REPORT but just for specified  customer not for all of them. 

Somebody know how to get list of all accounts ?

Thanks

Hi,

For get account hierarchy example, you need to set an MCC Id or clientCustomerId (a client/child account) in the clientCustomerId field of the property file as it will provide the account hierarchies based on the current clientCustomerId/MCC Id.

For your concern on Account Performance Report, if you want to download multiple reports from multiple client accounts under your MCC, then you need to use the parallel report download example.

Kindly do the suggestion first and let me know if you encounter any issues. If there are issues, then kindly provide your clientCustomerId as well as your SOAP request and response logs so I can further investigate. Please use the Reply privately to author option.

Thanks,

Vincent
