I am adding virtual product in PrestaShop using API and I am using PSWebServiceLibrary.
I have successfully added product and its images but when I am trying to add file to download for this product, I didn't find any method in above library and API.
So, I need any method to add downloadable file for virtual products in PrestaShop using API.
Also, I am using Prestashop's Kit Module which generates product kit from other products. I also need a method to add Stack and its details under Kit Module of a product via webservice or API. I have attached the screenshot of Kit Module that displays while adding or editing a product in PrestaShop.
