A promotion code, also know as a coupon code, is a code that is associated with a marketing discount. For example, a retailer might tell frequent customers to enter the promotion code "FX43B" to receive a 10% discount on their whole order. One or more unique promotion codes (may be numbers or strings) are associated with the discount. Promotion codes act as an eligibility requirement for the discount. When shopping, if the user enters a promotion code, the corresponding discount is looked up and applied if the all the conditions of the discount are met.
There are three types of promotion codes:
Public. Coupons that anyone can use. The coupons all use the same public coupon code.Note:You cannot export a public coupon definition or add coupons to a public coupon definition.
Private. Personalized coupons that you target to specific users. Private coupons have multiple coupon code identifiers.
Restricted. Coupons that are restricted to one user.
