How can I link a survey form to a product form then prepopulate a coupon code that will be used for a discount?

I would like to provide a discount to my products if they fill out a survey.  Can I link a survey form to my product form and then have it display a code when they complete it?

If the survey form and product form you're describing are both built with JotForm, then you can use URL PARAMETERS to prepopulate a coupon field on your product form. The general idea is to:

1. Have your users fill out the survey form

2. The survey form will be setup to redirect users to the product form

3. The URL that will be used for the THANK YOU PAGE REDIRECT would be the URL of your product form, plus the URL parameters to prepopulate a field (in your case, a textbox that will serve as a coupon).

For this setup to work, your product form should never be used to sell products/subscription. Instead, it should fetch a calculated value within your form. What needs to happen is for you to setup your products/subscriptions "outside the payment field" and manually calculate the total.

For these, you would need to create your products manually using textboxes, dropdowns, radio buttons, or checkboxes > assign calculation values to them > calculate the total and include the coupon within the calculation > and finally, pass the calculation to your payment field.

All the guides I linked above have example forms that you can fiddle around with, and they are accompanied with screenshots. So, give it a spin and if you see any problems along the way, don't hesitate to let us know so we can help.
