How to make coupons based on number of products selected by the user?

Is it possible to create a discount coupon based on the number of items selected? I want to create a 3 x 2 discount  if the number of items purchased is 3

Hi,

Unfortunately, the coupon codes on the payment tool are only set to Percentage and Fixed amount. 

For your reference: How to Add Coupon Code to Payment Forms

However, you can manually make a coupon code according to your preferences by adding a Short Text Field on the form builder.

Then apply Conditional Logic, which will calculate the number of items selected by the user.

Please note that Coupon Codes outside the payment tool are not hidden on the Source Code of the form, and advanced users might be able to find it.
