Delete a coupon 

You can delete coupons via the coupon management page of the Stripe dashboard. However, deleting a coupon does not affect any customers who have already applied the coupon; it means that new customers can’t redeem the coupon. You can also delete coupons via the API.

Parameters

No parameters.

Returns

An object with the deleted coupon’s ID and a deleted flag upon success. Otherwise, this call raises an error, such as if the coupon has already been deleted.

Promotion Code 

A Promotion Code represents a customer-redeemable code for a coupon. You can create multiple codes for a single coupon.

If you enable promotion codes in your customer portal configuration, then customers can redeem a code themselves when updating a subscription in the portal. Customers can also view the currently active promotion codes and coupons on each of their subscriptions in the portal.

Discounts 

A discount represents the actual application of a coupon or promotion code. It contains information about when the discount began, when it will end, and what it is applied to.
