This specification of the REST API for Shopping Cart includes the model definition as well as all available operations. Shopping Cart is the necessary component in modern sales channel both for online channel of e-commerce and call center and physical stores. It allows visitors to the shopping site to select items for eventual purchase. It provides a means of capturing a user purchase requirement, to accumulate a list of items for purchase, described as “placing items in the shopping cart” or “adding to cart.” It typically calculates a total charge for the cart including chosen goods or service, shipping and handling charges and the associated taxes are typically calculated during the checkout. Shopping cart supports purchase of both tangible and intangible good and service (e.g. mobile device or family plan). The charge includes the one-off fee such as the fee for handset and the recurring fee.  The customer will be informed about the fee information, but only pay the one-off fee after confirming the shopping cart. The recurring fee may be paid when reaching the bill cycle.
