I would like to let the customer pay the card fees when paying with a card. The PSP (eg QuickPay) has the posibility to deliver the fee amount with the API, but is it possible to include it in the amounts on the site before the actual payment window appears ? This is nessecary by law - it has to be stated clearly before the customer is presented the actual payment window from the PSP. You can see the Formal demands here:
learn.quickpay.net/helpdesk/en/articles/transactionfees/
If it is possible to include functions from the payment gateways in the Autoaction Code field, then that maybe could be a workaround ??
