Passing custom AJAX generated values through Zoho Web Form

Passing custom AJAX generated values through Zoho Web Form

Hi guys!

We are migrating to Zoho CRM, and one feature that we had with the CRM we previously used was the ability to pass a 'Coupon Code' (that is generated and displayed when our customer website is loaded) through the web form.

What would be the best method to pass this AJAX generated coupon code when a customer fills out the web contact form that Zoho creates?
