Cart Coupon

Module: Mage_Checkout

The Mage_Checkout module allows you to manage shopping carts and the checkout process. This module allows you to create an order once filling the shopping cart is complete.

Cart Coupon

Allows you to add and remove coupon codes for a shopping cart.

Resource Name: cart_coupon

Methods:

• cart_coupon.add - Add a coupon code to a quote
• cart_coupon.remove - Remove a coupon code from a quote

Note: In Magento, quotes and shopping carts are logically related, but technically different. The shopping cart is a wrapper for a quote, and it is used primarily by the frontend logic. The cart is represented by the Mage_Checkout_Model_Cart class and the quote is represented by the Mage_Sales_Model_Quote class.
