CustomerService getCustomers() throws CUSTOMER_NOT_FOUND

[Ivan Petrushev]

Hello,

I am trying to get information about the directly authorized user. 

API docs state calling CustomerService.getCustomers() can be used without clientCustomerId, but if I try to do it, I get this error:

> AuthenticationError.CUSTOMER_NOT_FOUND

I am using Python client library:

client = adwords.AdWordsClient(developer_token, oauth2_client, cache=googleads.common.ZeepServiceProxy.NO_CACHE)

customers = client.GetService('CustomerService', version='v201809').getCustomers()

This is the outgoing SOAP request:

{'SOAPAction': '\"\"', 'Content-Type': 'text/xml; charset=utf-8', 'authorization': 'REDACTED'}\n

<soap-env:Envelope

xmlns:soap-env=\"http://schemas.xmlsoap.org/soap/envelope/\">\n  

<soap-env:Header>\n    

<ns0:RequestHeader

xmlns:ns0=\"https://adwords.google.com/api/adwords/mcm/v201809\">\n      

<ns1:developerToken

xmlns:ns1=\"https://adwords.google.com/api/adwords/cm/v201809\">REDACTED

</ns1:developerToken>\n      

<ns2:userAgent

</ns0:RequestHeader>\n  

</soap-env:Header>\n  

<soap-env:Body>\n    

<ns0:getCustomers

xmlns:ns0=\"https://adwords.google.com/api/adwords/mcm/v201809\"/>\n  

</soap-env:Body>\n

Hi Ivan,

The CustomerService.getCustomers() when used without a clientCustomerId should return the accounts which the OAuth2 credentials has direct access to. When used with a clientCustomerId, it should return the details of that specific account only. That being said, could you confirm if the OAuth2 credentials you are using were generated using an email address which has access to an existing Google Ads account?

Additionally, so I can further investigate, could you provide your clientCustomerId and the email address you used to generate the credentials? You may send your reply using the Reply privately to author option.

Thanks and regards,
Peter
