Verified steps
Authenticate server-side requests with X-App-Id and X-App-Token headers from your Voucherify project settings.
Build a redeemables array (coupon codes, gift cards, promotion tiers/stacks, loyalty cards) attached to a customer and order payload, up to the documented per-call limit.
POST /v1/validations with the redeemables array to pre-check eligibility against validation rules before charging the customer.
POST /v1/redemptions with the same redeemables array to redeem the whole stack; capture the returned parent_redemption id.
If a later step fails (e.g. payment declines), POST /v1/redemptions/{parentRedemptionId}/rollbacks to roll back the full stack.
Known gotchas
Rollback always reverts the entire stacked redemption, not a single voucher within it, and is blocked once a redemption is too old.
Stacked/multi-redeemable redemption can only be triggered via the API — there's no dashboard UI to perform it manually.
Only one promotion_stack object is allowed per validation/redemption call, and each order ID can only be used in one in-flight request at a time.
