How to setup a quiz and see answers in Stripe

Hi! I've created a Typeform quiz and have that code to embed into our Squarespace site. This website sells monthly subscription boxes and I'd like visitors to take a quiz before they purchase but how do I lead them from a quiz and into a sale? Wondering if we can open the order in Stripe and see the user's quiz answers? For instance, if you go to StitchFix.com (similar business idea as ours- a subscription box)- you will see there is a pop up box 'take a quiz'- then it asks for your email or to create an account...I just don't know how to get to that point. Help and thank you!
