Add discounts for one-time payments
You can use discounts in Checkout to reduce the amount charged to a customer for one-time payments. Coupons and promotion codes allow for great flexibility in how you define and use them. They can:
- Apply a discount to an entire purchase subtotal
- Apply a discount to specific products
- Reduce the total charged by a percentage or a flat amount
- Create customer-facing promotion codes on top of coupons to share directly with customers
To use coupons for discounting subscriptions with Checkout and Billing, see how to apply discounts to subscriptions.
Checkout does not currently support discounting a purchase below the minimum charge amount for one-time payments.
Coupons specify a fixed value discount. You can create customer-facing promotion codes that map to a single underlying coupon.
This means that the codes
SPRINGPROMO can both point to one 25% off coupon.
Create a coupon
Coupons are created in the Dashboard or with the API:
If you want to create a session with an applied discount, pass the coupon ID in the
coupon parameter of the discounts array. Checkout currently supports up to one coupon or promotion code.
Configure a coupon
Coupons have the following parameters that you can use for one-time payments:
id, a unique identifier for the coupon
redeem_by, the latest date at which this coupon can be applied
applies_to, limits the products that the coupon applies to
The coupon object adds discounts to both one-time payments and subscriptions. Some coupon object parameters, like
duration, only apply to subscriptions.
Limit redemption usage
redeem_by values apply to the coupon across every application. For example, you can restrict a coupon to the first 50 usages of it, or you can make a coupon expire by a certain date.
Limit eligible products
You can limit the products that are eligible for discounts using a coupon by adding the product IDs to the
applies_to hash in the Coupon object. Any promotion codes that map to this coupon only apply to the list of eligible products.
Delete a coupon
You can delete coupons in the Dashboard or the API. Deleting a coupon prevents it from being applied to future transactions or customers.
Promotion codes are customer-facing codes created on top of coupons. You can also specify additional restrictions that control when a customer can apply the promotion. You can share these codes with customers who can enter them into Checkout to apply a discount.
Create a promotion code
To create a promotion code, specify an existing
coupon and any restrictions (for example, limiting it to a specific
customer). If you have a specific code to give to your customer (for example,
FALL25OFF), set the
code. If you leave this field blank, we’ll generate a random
code for you.
code is case-insensitive and unique across active promotion codes for any customer. For example:
- You can create multiple customer-restricted promotion codes with the same
code, but you can’t reuse that
codefor a promotion code redeemable by any customer.
- If you create a promotion code that is redeemable by any customer, you can’t create another active promotion code with the same
- You can create a promotion code with
code: NEWUSER, inactivate it by passing
active: false, and then create a new promotion code with
Promotion codes can be created in the coupons section of the Dashboard or with the API:
Enable user-redeemable promotion codes using the allow_promotion_codes parameter in a Checkout Session. This enables a field in Checkout to allow users to input promotion codes.
Configure a promotion code
With Promotion Code object parameters, you can customize eligible customers, redemptions, and other limits.
Limit by customer
To limit a promotion to a particular customer, specify a
customer when creating the promotion code. If no customer is specified, the code can be redeemed by any customer.
Limit by first-time order
You can also limit the promotion code to first-time customers with the
first_time_transaction parameter of the
restrictions attribute. If the
customer isn’t defined, or if a defined
customer has no prior payments or non-void invoices, it’s considered a first-time transaction.
Sessions that don’t create Customers instead create Guest Customers in the Dashboard. Promotion codes limited to first-time customers are still accepted for these Sessions.
Set a minimum amount
With promotion codes, you can set a minimum transaction amount for eligible discount by configuring the
minimum_amount and the
minimum_amount_currency properties. Since promotion code restrictions are checked at redemption time, the minimum transaction amount only applies to the initial payment for a subscription.
You can set an expiration date on the promotion code using
expires_at. If the underlying coupon already has
redeem_by set, then the expiration date for the promotion code can’t be later than that of the coupon. If
promotion_code[expires_at] isn’t specified, the coupon’s
redeem_by automatically populates
For example, you might have plans to support a coupon for a year, but you only want it to be redeemable for one week after a customer receives it. You would set
coupon[redeem_by] to one year from now, and set each
promotion_code[expires_at] to one week after it is created.
You can limit the number of redemptions by using
max_redemptions, which works similarly to the coupon parameter. If the underlying coupon already has
max_redemptions set, then the
max_redemptions for the promotion code can’t be greater than that of the coupon.
For example, you might want a seasonal sale coupon to be redeemable by the first 50 customers, but the winter promotion can only use 20 of those redemptions. In this scenario, you would set
coupon[max_redemptions]: 50 and
You can set whether a promotion code is currently redeemable by using the
active parameter. However, if the underlying coupon for a promotion code becomes invalid, all of its promotion codes become permanently inactive. Similarly, if a promotion code reaches its
expires_at, it becomes permanently inactive. You can’t reactivate these promotion codes.
You can delete promotions in the Dashboard or the API. Deleting a promotion prevents it from being applied to future transactions or customers.
