I want to create a webinar program that
1. Sends out an email invite
2. Change status when they fill out the gotowebinar form(the form hosted on gotowebinar)
3. send out confirmation.
I followed this doc. Create an Event with GotoWebinar - Marketo Docs - Product Documentation
I'm stuck at 2 though. I don't see a trigger for "fill out form" with gotowebinar form there.
Additionally, should I do 1 as a nested email program? or is it better to just create another step in the smart campaign to send out the invite?
