Hello Michal,

If you need to add it as payment system for the ecommerce then you need to get the variables generated by the ecommerce and send it to your PHP payment script.

The variables you can use are:

[PRICE] for the price the customer has to pay

[ORDER_NO] for the order number generated by the program

Which are the important ones you need to send to your payment system. If you need also further fields you can obtain these with following variables:

[NAME], [LASTNAME], [ADDRESS1], [ADDRESS2], [CITY], [STATEREGION], [COUNTRY], [ZIPPOSTALCODE], [EMAIL] and [PHONE]

The code can be added in step 4 - Shopping Cart | The Payment Type window in the Type Tab by choosing "Pay Now" and then "custom HTML code".

Unfortunately I cannot help you with the use of custom code, but if you have any doubts or issues on how to add them in the pages you made with WebSite X5 you can ask me.

Many thanks!
