Promocode

Kiwi can validates promocodes:

   kiwiSDK.promocode().validate("PROMOCODE", new PromocodeValidateListener() {
                    @Override
                    public void onSuccess(String applicationData) {
                    }

                    @Override
                    public void onInvalid() {
                    }

                    @Override
                    public void onError() {
                    }
                });
