Hi, The CLIENT_CUSTOMER_ID_INVALID <https://developers.google.com/adwords/api/docs/common-errors#AuthenticationError.CLIENT_CUSTOMER_ID_INVALID> error you are getting is due to the clientCustomerId being specified incorrectly. The correct format to be entered for the *clientCustomerId* value should be "*123-123-1234*". I hope this had been helpful.
If the issue persists, kindly provide the clientCustomerId that you are using and any SOAP request and response so I can better investigate the issue. Please reply using *Reply privately to author* for the requested information. Thanks and regards, Peter Laurence N.
