A promotion code points to an underlying promotion. You can optionally restrict the code to a specific customer, redemption limit, and expiration date.

## Returns

## Parameters

    If promotion `type` is `coupon`, the coupon for 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), and digits (0-9).

  If left blank, we will generate one automatically.
