Notification of Zendesk Error Message Change and Request for Unique Error Code

Hi All, Recently there was change in error message returned by Zendesk when a profile is processed. (Error message "This email is already taken. Try another email." was changed to "Email: is already being used by another user"). Since we had this error configured in our backend jobs, change in this message resulted in certain processes to fail.

We want to be notified of such changes in future so that we can take proactive measures to prevent processes from failing. Also, it would be helpful if we have a unique error code which  remains constant though the error content changes.
