Specifying the Items

In one CartCreate request, you can add up to ten items; the quantity of each item is set separately, as follows:

Item.1.OfferListingId=[Offer Listing ID]
Item.1.Quantity=3
Item.2.OfferListingId=[Offer Listing ID]
Item.2.Quantity=1  

This code adds two items identified by their OfferListingIds and the quantity of each item is set to 3 and 1, respectively.

You can use any combination ListItemIds and ASINs, or OfferListingIds in a single request to specify the items to add to a cart. You can only use one type of item identifier to add an item to a cart. You cannot, for example, use an ASIN and an OfferListingId in the same request to add the same item to a cart.
