Carts

A cart is basically a basket that customers put items into that they want to purchase. While Cortex API’s shopping cart has this as its core functionality, there is much more to this shopping cart than just that.

Key concepts developers should know about carts:

• A default cart is always available, registered users can create additional carts

• You can empty a cart’s contents

• All carts except the default cart can be deleted

• You do not need to create an order for the cart, an order is always available

• Cortex automatically persists carts between customer sessions so a customer can log on through a mobile phone and then log on through another device to complete the purchase

A cart’s line items is a collection of items that have been added to a cart. A line item can have one or more of the same items in it. For example, one line item can have seven Rocker T-Shirt or a single Rocker T-Shirt, but it won’t have one Rocker T-Shirt and a song track. The song track and T-shirt would be in separate line items.
