The Auth. Code (also known as the Authorisation Code or the Authorization Code) is a field available in the Raiser's Edge on Credit Card gifts. You can see an example of this field in the database view below.
Unfortunately, we have not been able to add this field to Importacular due to technical constraints. Should you wish to track an authorisation code from a third party system in the Raiser's Edge, we would recommend using a Gift Attribute, the Reference field or some other text based field.
