About the eCommerce Cart API

The cart is the first phase of a purchase, followed by checkout, then order.

A cart holds information about purchased items, prices, discounts, site details, buyer IDs (contact and member/visitor) and more. Additionally, some methods in the Cart API can directly manage the current cart of the site visitor or logged-in member.

With the eCommerce Cart API you can:

• Get a cart or the current cart.
• Add catalog items to a cart or to the current cart.
• Create a checkout from a cart or from the current cart.
• Estimate the price totals for a cart or the current cart.
• Update the properties of a cart or the current cart.
• Update the quantity of line items in a cart or the current cart.
• Remove a coupon from a cart or the current cart.
• Remove line items from a cart or the current cart.
• Delete a cart or the current cart.

You can also listen for events when a cart is created, updated, and deleted.
