What is promotion stacking?
Promotion stacking (also called promotion combining or mixing) is the possibility to combine different incentives (promo codes, auto-applied discounts, gift cards, referral codes, and loyalty codes) in a single transaction. Stacking can also define the order in which incentives should be applied. The stacking functionality is often accompanied by promotion exclusion rules that define which promo campaign can and cannot be used together.
How does stacking work in Voucherify?
Voucherify offers a separate stacking API that allows for the redemption of up to five redeemable in a single call. By using stacking API, users can effectively cut on the number of API calls needed per transaction and provide an overall improved customer experience. Note that this feature is currently in beta.
