Hi Ashish, The USER_PERMISSION_DENIED <https://developers.google.com/adwords/api/docs/common-errors#AuthorizationError.USER_PERMISSION_DENIED> error occurs when you are using OAuth2 credentials that has no access to the client account that you are targeting as your clientCustomerId.
With this, could you provide the SOAP request and response logs that was generated when you encountered the error as well as the email address that corresponds to your OAuth2 credentials? Please send this information via the *Reply privately to author* option. If you haven't enabled the SOAP logs yet, you can enable it by following this guide <https://github.com/googleads/googleads-java-lib#how-do-i-enable-logging> (in Java). Enabling of SOAP logs is also available to other client libraries that we support.
