HI, I am building salesfunnels (using clickfunnels) for local businesses in my community. The discounted services being offered in the funnel when bought will need a secure coupon code tagged to them. As of right now Clickfunnels does not have a solution that will work for me. Their coupons can easily be duplicated and are not secure for what I need them for (one time trackable use). I think I have found a solution called coupon carrier but there are alternative ways to do this through clickfunnels software with some programming. I need a solid solution and I am not great with clickfunnels software and or programming.
