Stripe type form conversions in Google adwords

I'm using a form which is resulting in purchases in type form through stripe terminal. People are being directed into the form from Google Ads. After using type form and making purchase through stripe they land on a thank you page.

I need exact purchase value from the process sent back to Google AdWords keywords that resulted in the purchase.

Google ad > landing page > typeform > last typeform step, stripe purchase > thank you page

The stripe purchase is an integration inside type form.
