I am implementing an ecommerce site which provides coupons to be used in partner sites. The coupons can be unique or same for all relying on some business. The concepts of coupon in EPiServer seems different. How to implement this?
What you can do is to implement your own ICouponFilter, then in
Filter(PromotionFilterContext filterContext, IEnumerable<string> couponCodes)
write logic to decide if a promotion should be excluded based on the provided coupons
@Quan Mai: What can be the purpose of Filter if the coupons are not used in my Site rather are used in other sites? Could you please elaborate?
