Discount Codes

With Discount Codes it is possible to give specific Cart Discounts to eligible customers. They are defined by a string value which can be added to a Cart so that specific Cart Discounts can be applied to the cart.

A DiscountCode can apply up to 10 CartDiscounts.

For an introduction to Discount Codes and to understand how they work in Composable Commerce, see the Discount Codes overview.
