I am attempting to add a ShoppingCartItem object with an ArtId to my ShoppingCart object using Inksoft's API 2.0.
I've been attempting to use SetCart but after a successful post the ArtId is always returned as null. I've used ArtIds returned from the SaveArt method as well as ArtIds from Inksoft's clipart.
I have the same issue with the Notes field, which I was hoping to use as a workaround.
