Creating a Custom Facebook Audience with Facebook Pixel

To create custom audiences for ads, we enable you to send two types of events to your Facebook pixel:

• When a customer submits a review ("ReviewSubmitted")
• When a customer visits your store through a Loox Referrals link ("LooxReferralsVisit") 

Follow these steps to send these events to your Facebook pixel:

1. Copy this code:

   <script>
   (function (report_fb_pixel) {
       var url_params = new URLSearchParams(window.location.search);
       var utm_campaign = url_params.get('utm_campaign');
       if (!utm_campaign) return;
   
   
       var rating = parseInt(url_params.get('rating'));
       var event_name = null;
   
   
       if (utm_campaign === 'loox-referrals') {
           event_name = 'LooxReferralsVisit';
       } else if (/^loox/gi.test(utm_campaign) && rating >= 1) {
           event_name = 'ReviewSubmitted';
       } else {
           return;
       }
   
   
       if (typeof fbq === "function") return fbq('track', event_name);
   
   
       !function (f, b, e, v, n, t, s) {
           if (f.fbq) return;
           n = f.fbq = function () { n.callMethod ? n.callMethod.apply(n, arguments) : n.queue.push(arguments) };
           if (!f._fbq) f._fbq = n;
           n.push = n;
           n.loaded = !0;
           n.version = '2.0';
           n.queue = [];
           t = b.createElement(e);
           t.async = !0;
           t.src = v;
           s = b.getElementsByTagName(e)[0];
           s.parentNode.insertBefore(t, s)
       }(window, document, 'script', 'https://connect.facebook.net/en_US/fbevents.js');
   
   
       fbq('init', report_fb_pixel);
       fbq('track', event_name);
   })('<YOUR-FB-PIXEL-ID>');</script>
   	

2. Paste the code in your theme.liquid file in your Shopify theme:
3. Replace <YOUR-FB-PIXEL-ID> with your Facebook Pixel ID
4. Click "Save

Note: If you'd like to only send "ReviewSubmmited" events starting from a certain minimum rating, edit the following piece of the code:

} else if (/^loox/gi.test(utm_campaign) && rating >= 1) {
