I'm creating a custom object to store event information from Cvent to a registrant's Marketo lead record. I only need to pull event title and registration type; therefore I've created my custom object (event title) and intermediary object (registration type). The next step shows that I need to add link fields to connect my intermediary object to a person/company and a custom object (event title); however I don't need any additional information from Cvent.
Are link fields necessary? If so, would registration type be a link field?
