How Can I Retrieve the 'applies_to' Field for a Coupon Using the Stripe API?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I am trying to retrieve the 'applies_to' field from a coupon using a GET request to the Stripe API.

My goal is to determine for which products the coupon is applicable.

I've reviewed the Stripe API documentation, but it's unclear whether the coupon object directly exposes the 'applies_to' value or if I need to implement additional logic, such as using metadata or expansion techniques.

Any guidance or examples would be appreciated.

Based on the current Stripe API documentation, the coupon object does not include an "applies_to" attribute that specifies which products the coupon is applicable to. A coupon is designed to represent a discount (either as a percent or fixed amount), and it may be applied to subscriptions, invoices, checkout sessions, and quotes. However, there isn’t a field on the coupon object that limits or defines its application to specific products.

For example, a typical GET request to retrieve a coupon returns a response like this:

BASH
curl https://api.stripe.com/v1/coupons/jMT0WJUD \ -u "sk_test_4eC39HqLyjWDarjtT1zdp7dc:"
JSON
{ "id": "jMT0WJUD", "object": "coupon", "amount_off": null, "created": 1678037688, "currency": null, "duration": "repeating", "duration_in_months": 3, "livemode": false, "max_redemptions": null, "metadata": {}, "name": null, "percent_off": 25.5, "redeem_by": null, "times_redeemed": 0, "valid": true }

Notice that there isn’t any "applies_to" property in the response. If you require the coupon to be tied to specific products, a common workaround is to manage such logic on your end. For example, you could use the coupon’s metadata to store product identifiers and then implement the logic in your application to restrict the discount usage based on those values.

If you have any additional questions about the Stripe API endpoints or coupon functionality, please let me know.

The applies_to property on the Coupon object is what Stripe calls an "expandable" property. This means it will be returned either as a string (when the property maps to a single object) or null. In this case applies_to is a nullable object containing a single property, products, so if you just make a plain retrieve call, you will get null.

Fortunately, the reason Stripe calls these properties "expandable" is that you can request the data to be included in the API call by passing the expand parameter. They have whole doc on how this works and it's definitely worth a read.

In your case, this would look something like the following

PYTHON
coupon = stripe.Coupon.retrieve('XXXXXX', expand=['applies_to']) print(coupon.applies_to)
