JotForm, Coupons and WooCommerce

We are looking for a way to generate dynamic, single-use coupon codes
when a customer is on our WooCommerce site. We use a JotForm to collect
information and based on a product serial number entered the customer is
eligible for anywhere from a 10%-40% discount.

At this point, the only way that we can figure that we can do this is to
have the customer complete the form, enter their email and then based on
the information entered, we set up a on-time-use coupon code in
WooCommerce and then email that customer the coupon code. This strategy
has two major drawbacks:

1. A lot of administration work on our part if we’re looking at many,
many hundreds of unique coupon codes

2. Poor customer experience since the customer is unable to buy the new
product from us until they receive the email with the unique discount code.

Ideally, we would like that the customer’s Shopping Cart already has the
discount applied based on their JotForm submission. The next best
scenario is that WooCommerce generates a unique, one-time code based on
the JotForm submission that the customer enters in the Shopping Cart to
get the discount.

Any ideas on how we can do this?
