How it works

Quote, redeem, rollback

The storefront only renders prices. Couponify decides eligibility, stacking, and final pricing, then records usage when payment succeeds.

The flow

  • Short-lived member JWT for browser quote requests
  • Signed merchant server calls for redeem and rollback
  • Rule priority, exclusivity, and opt-in stacking
  • Automatic usage restoration on refunds

Why Couponify

Stop reinventing promotion logic

Merchants should not build promotion engines in custom JavaScript. Couponify pushes that complexity into auditable APIs.

Server-side truth

All discount logic lives in Couponify APIs. Storefronts never drift from checkout math.

Membership-first pricing

Turn paid memberships into instant discounts, exclusive prices, and capped usage benefits.

Fast integration

Ship with one browser SDK, a hosted member login flow, and signed server callbacks.
