We are using only the checkout page, not the actual order/cart shop, and we are pushing specific order_id(s) to the cart directly from our POS. When a customer finishes the checkout process and a transaction is processed with a gateway (SecureNet for us), we need to be able to directly pair exported transactions from the gateway provider with our transaction/order id. Unfortunately, the FoxyCart registers only it's own transaction id with the gateway, not our order_id, and so the actual pairing is not possible without additional hooks and processing. Is there a way to push a comment, or some other kind of field (numeric value would be enough) to the checkout, which would be passed to the gateway provider unchanged?
Thanks for your help,
