I would like to include ipayment 1&1 in a credit card payment processor modul in my Virtuemart Shop 1.1.5 & Joomla 1.5.22.
The modul is included ([url removed, login to view]), but needs to be set up for the connection with the ipayment server.
I use [url removed, login to view] (German) with ipayment (German) as payment gateway.
I do not wish to be redirected to the ipayment website. The modul should be on the checkout page(3), as usual.
The transaction must be done completely on the ipayment server (PCI).
