I want to collect contact details for invitees using a Google form created for this purpose. I want the respondents who give me their contact details to also input an appointment entry in a public calendar.
To maintain their privacy, I should not ask their names in the public calendar. I need them to input their unique ID so I can link their calendar's entry with their form contact details. I need a public calendar so they do not pick a conflicting data taken by another respondent.
Is there any way to show a random ID for a Google form respondents? If not, are there any suggestions to link public calendar entries with contact details to contact the person?
