### Coupon restriction types
The following coupon description types are available:
- `restrict-to-countries`: Restricts a coupon for use in specific countries.
- `discounts-per-redemption`: Restricts the number of times that the coupon can be applied by one redemption.
For example, use this restriction to configure a coupon that can only be applied to the first subscription renewal of a particular product.
- `minimum-order-amount`: Sets a minimum order amount for a coupon application.
For example, if the restriction amount is $20, the coupon is only applied to invoices with a total amount of $20 or more.
- `restrict-to-invoices`: Restricts a coupon to specific invoices.
- `restrict-to-plans`: Restricts a coupon to specific pricing plans.
- `restrict-to-subscriptions`: Restricts a coupon to specific order subscriptions.
- `restrict-to-customer-tags`: Restricts a coupon to customers with specific tags.
- `restrict-to-customers`: Restricts a coupon to specific customers.
- `restrict-to-exclusive-application`: Restricts a coupon so that it cannot be used in combination with other coupons. If more than one coupon is active, a coupon with this restriction is only applied if it provides a larger discount than the other coupons combined. If a coupon with this restriction is applied, all other coupons are removed.
- `restrict-to-products`: Restricts a coupon to specific products.
- `paid-by-time`: Specifies a date and time at which a coupon redemption expires if not paid.
- `redemptions-per-customer`: Restricts the number of times that a coupon can be redeemed by one customer.
For example, use this restriction to limit the number of redemptions to one per customer.
- `total-redemptions`: Restricts the number of times a coupon can be redeemed by different customers.
- `restrict-to-bxgy`: Provides "buy X get Y" promotions.
These promotions incentivize new customers to buy and also reward existing customers.
This restriction type enables you to add discounted plans to an invoice when a certain quantity of other plans are purchased.
For example, if a customer buys two or more books, they get one free bookmark.
