How do I display an invoice download button on specific template files?

In order to display an invoice download button, add the below code for example to your “thank you” page or “customer-completed-order” email template.

echo do_shortcode( '' );

For use in WordPress editor use below shortcode. This will only work if you replace “ORDER_ID” with an actual order id.

Note: Download button will only be displayed when PDF exists and order has been paid.

Please test the functionality on a development environment of your website. If it ceases to work, please revert back to the original state of your website and follow the tutorial again.
