    Promo Code Validation?

    Asked by Domingo Corona  on October 01, 2015 at 06:07 PM

    Can jot form do promo code validation?  I saw that it could do it with conditions. The problem is that we have 50k promo codes. Also, we would need to invalidate the code after it gets used.

    Here is what i tried with conditions:



    Basically, we want the customer to input a promo code, if it's valid download a file, if invalid (or has already been used), get an error message.

    Thank you,

    Domingo Corona

    Unfortunately, I think Jotform is not designed to handle 50k conditions as you would need to add a condition for each 50k promo codes and this might crash the browser. 

    You may, however, do your validation using custom PHP script hosted on your website. You can do that by sending post data from Jotform using Custom Thank You Page.
