In the GiveCampus API fields, the information for the donor name is contained in a single field called the "Paid By Name". In order to break this field into the respective parts, we recommend that it is used with the Name Parser tool in Importacular. To learn more about the Name Parser tool, please see this article.
To see this in action, you can watch this video.
