One of the way would be create a survey with required question types and take couple of test responses. Now using this API we can retrieve a response and understand how it is stored in Qualtrics.

Thanks Shashi, that would progress things. I’m hoping for a documented holistic resource so I don’t have to find out through trial and error.

This support article describes different field types: https://www.qualtrics.com/support/vocalize/dashboard-settings-cx/dashboard-data/data-compatibility/

@moldy This give you the list of question type, in each one of them there’s a section of Data & Analysis where you can get what you want.

Hope this helps
