tapfiliate integration with Squarespace

Site URL: https://myinnoportal.com

Hi everyone, 

Please can someone guide me on implementing an affiliate program with Squarespace. 
I will need to set different commission types for varies products. It's all in Javascript.

I'm not sure how to use the below code: 

<script src="https://script.tapfiliate.com/tapfiliate.js" type="text/javascript" async></script>
<script type="text/javascript">
  (function(t,a,p){t.TapfiliateObject=a;t[a]=t[a]||function(){
  (t[a].q=t[a].q||[]).push(arguments)}})(window,'tap');

  tap('create', 'YOUR ACCOUNT ID');

  var myOrder = {}; // get from your server

  var commissions = myOrder.lineItems.map(function(lineItem) {
    return {
      sub_amount: lineItem.subTotal,
      commission_type: lineItem.product.sku
    };
  })

  tap('conversionMulti', 'UNIQUE CONVERSION ID', {}, commissions);
</script>
