API ReferenceCoupons
Overview
Create discount codes and choose who, what, and when they apply to.
Coupons apply an amount or percentage discount when a customer supplies a code. Choose which products qualify, how often the code can be used, and when it is valid. For discounts that apply without a code, use Promotions.
The response fields products and product_variants contain explicit product
and variant IDs that determine where the coupon applies.
Coupons and their linked products must belong to the selected store. Track batch requests in your integration and check what changed after a lost response before retrying; batch writes do not have a general idempotency guarantee. Each endpoint documents its discount units, limits, and date fields.
