Hi,
So what they are saying is that to pass additional data to Virtual Merchant the merchant has first to configure custom fields in his virtual merchant account and then have the integration plugin fill in those fields with the corresponding data.
So that means that every merchant can potentially have different fields for different data to be passed.
First, as I said before, this has never been supported by the VirtualMerchant plugin so it's not possible that an update of HikaShop removed that.
And second, I don't see an easy way to make that generic. And it will be really ugly. Because you need to have one field per product, and then, how do you handle the quantity of each product, the options of the products the characteristics, the custom fields entered, etc. Sure it could be hacked into the payment plugin for your specific case. But in that case, that's custom development. You can do that in the code of the file plugins/hikashoppayment/virtualmerchant/virtualmerchant.php
