Can anyone assist with my third party pixel tracking issue?

[maxinweb]

I am having problems with the tracking pixel.
I consulted this page: https://help.shopify.com/en/manual/orders/notifications/email-variables#order-fulfillment and changed total_price to subtotal_price
I would like to receive from Shopify on my pixel the subtotal_price ( The subtotal doesn't include taxes (unless taxes are included in the prices) or shipping costs.)

Can anyone help me with this?
I entered this pixel on Shopify but I keep getting the total_price

This is the pixel:

<img src="https://tr.traffeffy8.com/p?o=20920528&m=13144&t=i&sale={{ subtotal_price | money_without_currency }}&adv_sub4={{ subtotal_price | money_without_currency }}&adv_sub5={{ order_number }}&currency={{ currency }}" width="0px" height="0px">

===========================

<script src="https://web-resources.offer18.net/sdk/web/WebSDK.js">

<script>

    window.Offer18WebSDK.activateDebugMode();

</script>

<script>

    window.Offer18WebSDK.trackConversion({

        domain: 'tr.traffeffy8.com',

        accountId: ’13144’,

        postbackType: ’’, // 'iframe' or 'pixel'

        isGlobalPixel: true,

        allowMultiConversion: false, // true or false

        conversionData: {

            sale: '{{ subtotal_price | money_without_currency }}',

            currency: '{{ currency }}',

            adv_sub1: '{{order_id}}',

            adv_sub4: '{{ subtotal_price | money_without_currency }}',

            adv_sub5: '{{ order_number }}',

        }

    })
