Hi,
I've got the Community Edition (5.5.0) working fine but I'd like to ask if it's possible to include fields (from a contacts/leads form) within the tracker URL please? My tracker URL does a redirect to a registration form (php) and I'd like to pass an 'invite code' to the form. This code would come from some field on the lead form.
I can't figure out how to do this so don't know whether it's even possible. Can anyone advise please.

Tks,
Alex
