Hi there, The error CUSTOMER_NOT_FOUND <https://developers.google.com/adwords/api/docs/common-errors#AuthenticationError.CUSTOMER_NOT_FOUND> means that there is no account found for the customer ID provided in the header.
Could you double-check if the clientCustomerId you're using is correct by running ManagedCustomerService.get() <https://developers.google.com/adwords/api/docs/reference/v201809/ManagedCustomerService#get> in your manager account? If you verify that it is indeed correct and that ManagedCustomerService.get() <https://developers.google.com/adwords/api/docs/reference/v201809/ManagedCustomerService#get> returns the clientCustomerId you're using, then please provide the complete SOAP request and response logs via *Reply privately to author* and the account logged in when you're generating your OAuth2 credentials so I can look into this more.
