I could use a little help. I'm writing (or at least trying to write) a payment module for Stormpay IPN utilizing the 3rd party cart feature (which itemizes product/qty/price). So far so good, untill I come to CCGV support.
I'm looking for a concise block of code to extract the coupon/gv info, much as is done in checkout_confirmation.php, so I can pass it on to Stormpay as individual line items. Oy! I've been all over your wonderful contribution (which I use extensivly), but with no success.
Any suggestions would be appreciated.
