My payment provider told me that I can myself simply implement the payments methodes:

"Copy this example code to a file iDealExampple.php and set the 5 parameters in the top to
make iDeal transactions. You may connect this script to your webshop by adding code to the
functions StartTransaction, HandleReporturl and to the result of the returnurl.

Which code?

Vero

iDeal is paymentmethod nr.1 in Netherlands, like Sofort banking in Germany. 15 000 000 transactions in december.

Thanks,
Vero
