Looking for Marketo Event Check-In App Guidance
Have I set up the program correctly for the Marketo Event Check-In App to work?
Here is my program setup:

Assets:

I plan to send an invitation email that has the landing page link. Customers will fill out the form on the landing page and go through the triggered Registered flow.
Did I miss any steps in the setup? Also, if I have someone that attends the trade show that wasn't in my program and not in my database, would I be able to add that person?
Thanks
Danielle
