I'm using Gravity Forms with an SSL certificate in England and need to take customer payments via a Credit or Debit card in £'s. I really don't want to use PayPal, as I have a Stripe account.
My form has a Coupon/Discount Code so the total amount could be reduced by 100% to £0 which means I don't need to take their CC details. In this instance I just want the form to submit successfully. If the total is a positive amount then payment details would need to be entered before the form submits.
Can anyone point me to a payment plugin that only kicks in if the value of the transaction is above £0?
