I want to sent out a survey for people to choose an attendance date and have to automatically present them with a calendar invite file.
Yes it does Dominic. Thanks for getting me going the right direction!
SurveyGizmo has this documented solution for adding .ICS files to your survey:
This solution does not automatically present the survey respondent with the event, but I’m thinking you could add the necessary .ICS files each to their own Text Element and then you could use Question Logic to trigger the appropriate calendar event based on the selected attendance date.
I hope this helps you get started!
