Hello Franz,

You can integrate any payment system by adding the custom HTML code you receivd for this payment in the e-commerce section in the payment type section by adding a new payment type and then in the Type tab choose "pay now" and "custom HTML code". It will show a field where you can enter the custom payment HTML code:

You will need to add in the custom code the variables:

[ORDER_NO] - the order number is entered here;

[PRICE] - the price is entered here.

Many thanks!
