Coupon

A coupon contains information about a percent-off or amount-off discount you
might want to apply to a customer. Coupons may be applied to [subscriptions](https://api.stripe.com#subscriptions), [invoices](https://api.stripe.com#invoices),
[checkout sessions](https://docs.stripe.com/api/checkout/sessions), [quotes](https://api.stripe.com#quotes), and more. Coupons do not work with conventional one-off [charges](https://api.stripe.com#create_charge) or [payment intents](https://docs.stripe.com/api/payment_intents).

# `t`

```elixir
@type t() :: %Stripe.Resources.Coupon{
  amount_off: integer(),
  applies_to: Stripe.Resources.Coupon.AppliesTo.t() | nil,
  created: integer(),
  currency: String.t(),
  currency_options:
    %{required(String.t()) => Stripe.Resources.Coupon.CurrencyOptions.t()} | nil,
  duration: String.t(),
  duration_in_months: integer(),
  id: String.t(),
  livemode: boolean(),
  max_redemptions: integer(),
  metadata: %{required(String.t()) => String.t()},
  name: String.t(),
  object: String.t(),
  percent_off: float(),
  redeem_by: integer(),
  times_redeemed: integer(),
  valid: boolean()
}
