Add discounts

Learn how to apply discounts with coupons and promotion codes in your custom integration.

You can use discounts with the Checkout Sessions API to reduce the amount charged to a customer. Coupons and promotion codes allow you to:

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

Payment Intents API

If you use the Payment Intents API, you can apply discounts by calculating the discounted amount server-side, and creating or updating the PaymentIntent with the adjusted amount.

Create a coupon

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 the related setting and the related setting can both point to one 25% off coupon. You can create coupons in the Dashboard or with the API:

Configure a coupon

Coupons have the following parameters that you can use:

currency
percent _ off or amount _ off
max _ redemptions
redeem _ by : The latest date customers can apply the coupon
applies _ to : Limits the products that the coupon applies to

Limit redemption usage

The max_redemptions and 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.

Create a promotion code

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 during checkout to apply a discount.

To create a promotion code, specify an existing coupon and any restrictions (for example, limiting it to a specific customer or customer_account). If you have a specific code to give to your customer (for example, the related setting), set the code. If you leave this field blank, we’ll generate a random code for you.

The 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 code for 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 code .
You can create a promotion code with code: the related setting , inactivate it by passing active: false , and then create a new promotion code with code: the related setting .

Promotion codes can be created in the coupons section of the Dashboard or with the API:

On your client, use applyPromotionCode to apply a promotion code that your customer enters. Use removePromotionCode to remove all previously applied promotion codes.

index.html

<input type="text" id="promotion-code" />
<button id="apply-promotion-code">Apply</button>
<button id="remove-promotion-codes">Remove</button>
<div id="promotion-code-error"></div>

checkout.js

const checkout = stripe.initCheckoutElementsSdk({clientSecret});
const loadActionsResult = await checkout.loadActions();
if (loadActionsResult.type === 'success') {
 const {actions} = loadActionsResult;
 const input = document.getElementById('promotion-code');
 document.getElementById('apply-promotion-code').addEventListener('click', () => {
 actions.applyPromotionCode(input.value).then((result) => {
 if (result.error) {
 // Display an error message
 document.getElementById('promotion-code-error').textContent = result.error.message;
 } else {
 // Clear the input if the promotion code was successfully applied
 input.value = '';
 }
 });
 });
 document.getElementById('remove-promotion-codes').addEventListener('click', () => {
 actions.removePromotionCode();
 });
}

Configure a promotion code

For each promotion code, you can customize eligible customers, redemptions, and other limits.

Limit by customer

To limit a promotion to a particular customer, specify a customer or customer_account when creating the promotion code. If no customer is specified, any customer can redeem the code.

Limit by first-time order

You can also limit the promotion code to first-time customers with restrictions.first_time_transaction. If a customer or customer_account isn’t defined, or if a defined customer or customer_account has no prior payments or non-void invoices, it’s considered a first-time transaction.

Note

Sessions that don’t create a customer create a guest customer in the Dashboard instead. 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 minimum_amount and minimum_amount_currency. Since promotion code restrictions are checked at redemption time, the minimum transaction amount only applies to the initial payment for a subscription.

Customize expirations

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 expires_at.

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 can set coupon[redeem_by] to one year from now, and set each promotion_code[expires_at] to one week after it’s created.

Limit redemptions

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 can set coupon[max_redemptions]: 50 and promotion_code[max_redemptions]: 20.

Inactive promotions

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 max_redemptions or expires_at, it becomes permanently inactive. You can’t reactivate these promotion codes.

Delete promotions

You can delete promotions in the Dashboard or the API. Deleting a promotion prevents it from being applied to future transactions or customers.
