You can review this user guide : How-To-Add-Coupon-Code-in-the-Payment-Form
But do take note that coupon code discount will only work for payment type that involves selling products.
It will not work of you are using Donation or custom amount payment type.
If you were using the method to pass the payment amount to payment field as described here , you may need to integrate your coupon code discount on the field/widget you used outside the payment tool.
I am referring to your thread here https://www.jotform.com/answers/1024319
Hope this help. Let us know if you need further assistance.
