How to embed an infusionsoft form into a thank you page?

We are trying to have our thank you page, that displays after a purchase, have an infusionsoft form on it so it will update the Contact record with information provided in that form. We have been unsuccessful in getting this to work. Basically, we are wanting something like the “referral partner snippet” on the actual thank you page. Is this possible? Has anyone tried something like this before?

Can you share a bit more information with the community on this. What are you using for the checkout experience. Is this through the Infusionsoft Shopping Cart experience, or an Orderform.

Also, what are you currently using for your thankyou page?

I feel like there may be a solution here, but I wanted to see if you could share a bit more about what your current setup for checkout is like, and where you are running into, in terms of issues.
