Phase 1: Authentication Update for the XML based API

This guide will help you get started with the new authentication process into the XML based API.  This will not affect clients that are already on the new JSON API through this Developer Portal.  The only change for Phase 1 will be the log in request for our existing XML API users.  This authentication process must be completed and implemented into your application by January 1, 2020.  Any applications on the XML based API not using this system will no longer have access into our API.
