Maxio Coupons API
The Coupon object defines a discount, either a percentage or a fixed amount, that can be applied to a subscription to reduce the subscription's billing amount. Coupons can be restricted to a specific Product Family, limited to a date range, and configured to apply once or recur over a set duration.
