How to list products from b2b api?

im a simple user (reseller) and i got a b2b api key with some sample code. I want to list all the products from a company. I have a website (simple bootstrap3 (html,css)), not webshop. I just want to list on a page.

The Sample Code:

https://api.wycena.keno-energy.com,
POST: {
    "apikey": "A5TTRfG453d24F",
    "method": "GetProductsList",
    "parameters": [
            {
                "ShowGroups": "1",
                "ShowIndex": "1"
            }
    ]
}

I want to write out: GetProductInfo ; GetProductList ; GetProductsWarranty.

How can i get these? thank you for helping. I have wampserver, js.node and sublime text.
