## Parameters

- [`promotion`](https://docs.stripe.com/api/promotion_codes/create.md?query=promotion) (object, required)
  The promotion referenced by this promotion code.

- `active` (boolean, optional)
  Whether the promotion code is currently active.

- `code` (string, optional)
  The customer-facing code. Regardless of case, this code must be unique across all active promotion codes for a specific customer. Valid characters are lower case letters (a-z), upper case letters (A-Z), digits (0-9), and dashes (-).

  If left blank, we will generate one automatically.

  The maximum length is 500 characters.

- `customer` (string, optional)
  The customer who can use this promotion code. If not set, all customers can use the promotion code.

- `customer_account` (string, optional)
  The account representing the customer who can use this promotion code. If not set, all customers can use the promotion code.

- `expires_at` (timestamp, optional)
  The timestamp at which this promotion code will expire. If the coupon has specified a `redeems_by`, then this value cannot be after the coupon’s `redeems_by`.

- `max_redemptions` (integer, optional)
  A positive integer specifying the number of times the promotion code can be redeemed. If the coupon has specified a `max_redemptions`, then this value cannot be greater than the coupon’s `max_redemptions`.

- `metadata` (map, optional)
  Set of [key-value pairs](https://docs.stripe.com/api/metadata.md) that you can attach to an object. This can be useful for storing additional information about the object in a structured format. Individual keys can be unset by posting an empty value to them. All keys can be unset by posting an empty value to `metadata`.

- [`restrictions`](https://docs.stripe.com/api/promotion_codes/create.md?query=restrictions) (object, optional)
  Settings that restrict the redemption of the promotion code.
