Sending WooCommerce cart info to Gravity Forms

So I have a unique situation. Client wanted a survey customers can fill out, link to the survey is prompted from the cart page.
I've got the survey setup via Gravity Forms and all is well but the client would like a record of what the customer had in their cart at the time they filled out the form.
The only option I can think of is passing the cart info to gravity forms via a query string … But I'm not sure how to get the data pushed from the cart to the query string (or if this the the best way to go at all.). Any suggestions would be great.
