class Stripe::Coupon

def self.delete(id, params = {}, opts = {})

You can delete coupons via the [coupon management](https://dashboard.stripe.com/coupons) 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. 
def self.delete(id, params = {}, opts = {})
  request_stripe_object(
    method: :delete,
    path: format("/v1/coupons/%<id>s", { id: CGI.escape(id) }),
    params: params,
    opts: opts
  )
end
