Coupon Codes

Hi @emmaswl

We will check if it is possible to do via customization.

Could you please let us know whether you’re using the default WooCommerce coupon functionality or a third-party plugin to generate the coupon codes?

Looking forward for your reply.

Hi @emmaswl

Thank you for the information.

You can use the below filter to show the coupon code in delivery notes:

add_filter( 'wcdn_order_info_fields', function( $fields, $order ) {
    $coupons = $order->get_coupon_codes();

    if ( ! empty( $coupons ) ) {
        $fields['coupon_code'] = array(
            'label' => __( 'Coupon', 'woocommerce-delivery-notes' ),
            'value' => implode( ', ', $coupons ),
        );
    }

    return $fields;
}, 10, 2 );

Please add this filter in your theme’s function.php file or via Code Snippets plugin.

Let us know if there are any further issues.
