Link directly to checkout and automatically add a product to the cart from outside webflow

I have a 3rd party survey where people answer questions and get product recommendations. At the end of the survey, we know exactly what product people need, so I’d love to redirect them at the end of the survey(again, not in webflow) directly to my webflow site, have them bypass the product page and cart page and go directly to checkout with the product added and ready for purchase.

This needs the ability to add a product to the cart automatically, or do a checkout without a cart.
The product has no shipping or options.

Is there a way to do this?
