Passing Subscriber ID to Airtable / typeform

Hi there,

I want to be able to give my members a series of forms which they can complete, in order to build a growing dataset of answers against their profile.
I’m trying to work out how to pass an ID / email of a subscribed member automatically through a form when they complete it (after logon), which I can then store in something like Airtable.

Has anyone got any experience of passing any kind of member ID automatically that could point me in the right direction?

Many thanks in advance!
