Hi Shari,
Thanks for the example. From what I understand, Cvent does not allow you to put any code on their pages and therefore you cannot put the Munchkin code on their registration pages. However, depending on your use case their may be a technical work around to achieving you goal.
I imagine you are trying to tracking visitor engagement with the Cvent registration page, as that is the typical application for the Munchkin tracking code. However, I am curious about your intended use case. Can you share your thoughts with me on your objective?
