How can I detect if a one-off Stripe payment used a coupon?

Want to use over 200+ MCP servers inside your coding tools like Cursor?
In the Stripe Dashboard, payments show both the original price and the discounted price (with the Coupon id) under the "items" section. However, when I retrieve a payment via the API, there is no information about any applied discounts or coupons.
I’m specifically referring to one-off payments (not subscriptions) where the coupon details appear in the invoice object. The payment object doesn't seem to provide this information. Is there a recommended workaround or method to determine if a coupon was applied when using the Stripe API?
Thanks in advance for any guidance!

When using one-off payments with the Payment Intents API, coupon or discount details aren’t attached to the payment object because coupons are not supported for conventional one-off charges. This is why you see discount information in the Dashboard (typically coming from an invoice’s “items” section) for payments that are tied to an invoice or subscription, but not in the Payment Intent itself.
Options/Workarounds:
- If you need to track which coupon was applied for a one-off payment, you’ll need to capture that information yourself (for example, by including the coupon data in your metadata when creating the Payment Intent).
- Alternatively, if you want Stripe to handle discounting, you can use the Checkout Session or create an invoice so that the coupon and discount details are preserved in the related invoice object.
These approaches are necessary because the API does not return coupon or discount information for one-off Payment Intents directly.

You can find the applied coupons/discounts at the invoice Object level[1]. If there are many, you can expand[2] the discounts field[3].
