Is this the correct or recommended way to add item(s) to cart via URL in SuiteCommerce? Ref 1: http://www.netsuiterp.com/2018/09/add-item-to-shopping-cart-through-link.html Ref 2: https://www.netsuiterp.com/2018/09/add-multiple-items-to-shopping-cart-and.html

These are vestigial from the WSDK. They still 'work' but are not generally recommended for SCA where you have other, better ways of adding to the cart.
