Has anybody been able to integrate the discount contribution with PayPal IPN? I ask because I have added both and both work up to a point.
I assume the table discount_coupons_to_orders gets updated every time a coupon is used so that when a coupon is redeemed by a customer, it's checked against the maximum number of times it can actually be used (minus how many times it's already been used in discount_coupons_to_orders). As a result, that table doesn't seem to get updated because of the PayPal IPN process (as I believe it bypasses the discount_coupons_to_orders table update in checkout_process.php) which means the coupon can be used forever or until it hits the coupons_date_end as it's use isn't ever recorded.
After looking at this problem for the last few hours and trying to come up with a solution that works...my head hurts. :blink: Is there any solution?
I would very much like to use this contribution, but without some sort of solution, I'll have to remove it as I need the PayPal IPN more than coupons.
I apologize in advance if this question has been answered already, but I couldn't find a solution in the support thread for this contribution.
