I have a script for conversion tracking, for Justuno, it is to go onto my GTM, I have a wordpress site. I just need the gaps filled in ie order id etc, please read script <script data-cfasync="false"> window.juapp=[login to view URL]||function(){(window.juapp.q=window.juapp.q||[]).push(arguments)} /* Replace the [order ...] portions below with the actual order information. You can omit any of the attributes that you don't have values other then the order id and order total. */ juapp( 'order', '[order id]', {total:[order total],subtotal:[order subtotal],tax:[order tax],shipping:[order shipping],currency:'USD'} ); /* You will need to repeat this line of code for each item in the order. Replace the [item ...] portions below with the actual item information in order. You can omit any of the attributes that you don't have values other then the item id and quantity. */ juapp( 'orderItem', '[item id]', {name:'[item name]',quantity:[item quantity],price:[item price],color:'[item color]',size:'[item size]'} ); /* end of repeat section */ </script>
