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.

With the eCommerce Cart API you can:

• Get a cart.
• Add catalog items to a cart.
• Create a checkout from a cart.
• Estimate a cart's price totals.
• Update a cart's properties and line items quantity.
• Remove a coupon.
• Remove line items and delete a cart.

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