Is it possible to get a cart link from a quote ID create from the magento API. ie I want to add items to the cart using the magento API that would be initiated from a 3rd party website. And when they are ready to check out id have provided them a link to their magento cart.
Returns: Type Description int ID of the created empty shopping cart
You would have to create your own link and controller to reload the cart. Take a look at Programmatically add items to cart and assign to guest user
ricv, first, you want to add product using using soap api for third party site:
2.add Product in quote:http://www.magentocommerce.com/api/soap/checkout/cartProduct/cart_product.add.html
your is register customer ,then Allows you to move products from the current quote to a customer quote.
