Using the HTML integration, the basket is managed automatically. You just need to define the articles.

data-sc-item-tax: the VAT rate in percent;
data-sc-item-price: the gross unit price in the smallest currency unit;
data-sc-item-quantity: the amount as integer.

data-sc-item-ean: the official EAN (or GTIN) of this product.
