  // the UserPaymentOption.
  // For instance, if the booking is canceled, the UserPaymentOption should
  // reflect an additional credit to the user. In the case of a multi-use
  // payment option, the current_count should be increased by one to
  // allow the user to create another booking with this payment option. In the
  // case of a single-use payment option, a new single-use user payment option
  // should be returned. (required if altered in update)

  // error (e.g., booking is not cancellable) (required if failure occurs)
