We are wanting create invitations for our customer webinars that our partners can send out to their prospect/customer base. As the contacts register for the webinar we want to be able to identify which partner they came from so we know who we should assign the lead to. We have a large Partner community so manually creating the Landing Page URL's and placing them into individual emails won't work. Does anyone know if a customized token or field can be built to generate a dynamic URL?
