AuthenticationError.CUSTOMER_NOT_FOUND

[Nick Zhu]

Hi guys,

For the past few days we've been seeing a lot of exceptions due to AuthenticationError.CUSTOMER_NOT_FOUND.

Google.Api.Ads.AdWords.Lib.AdWordsApiException: An API exception has occurred. See ApiException and InnerException fields for more details. ---> System.Web.Services.Protocols.SoapException: [AuthenticationError.CUSTOMER_NOT_FOUND @ ; trigger:'<null>']
   at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)
   at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)
   at Google.Api.Ads.Common.Lib.AdsSoapClient.MakeApiCall(String methodName, Object[] parameters)
   --- End of inner exception stack trace ---
   at Google.Api.Ads.Common.Lib.AdsSoapClient.MakeApiCall(String methodName, Object[] parameters)
   at Google.Api.Ads.AdWords.v201409.ManagedCustomerService.get(Selector serviceSelector)

We're using the C# .NET library, are you guys aware of any issues with this call, or do you know anything about this error ?

Thank you very much,

Nick

Hi Nick,

Did this happen to your existing account created a long time ago? 

Or did this happen to your newly created account?

Can you provide request and response SOAP logs (with your credential information stripped)?

Best,

We are trying to get those information. Before that could you please tell us under what scenarios will this error be thrown?

Hi,

Usually, this error means that no account found for the customer ID you provided in the header.

This might be because the account has just been created and not established in the backend yet.

That's why I asked you if you have created this account just recently.

Cheers,
