Add Antlytics to Google Tag Manager

Prerequisites

• An Antlytics account (sign up free)
• Your tracking ID from Settings → Tracking Snippet in your Antlytics dashboard

Install the snippet

1. In your GTM workspace, click Tags → New.
2. Set the Tag type to Custom HTML.
3. Paste the snippet into the HTML field.
4. Under Triggering, choose All Pages (or the trigger you prefer).
5. Save the tag and Submit your container to publish.

Tip: Direct snippet installation (without GTM) reduces complexity and avoids the extra round-trip GTM introduces. GTM is a good option if you are already using it to manage other tags and prefer a single deployment workflow.

  function sid(){
    try{var s=sessionStorage.getItem(k);if(s)return s;
      s=crypto.randomUUID();sessionStorage.setItem(k,s);return s;}
    catch(e){return crypto.randomUUID();}
  }
  function utm(){
    try{var p=new URLSearchParams(location.search),o={};
      ["utm_source","utm_medium","utm_campaign","utm_term","utm_content"]
        .forEach(function(k){var v=p.get(k);if(v)o[k]=v;});
      return o;}
    catch(e){return {};}
  }
  function send(){
    fetch(u,{method:"POST",headers:{"Content-Type":"application/json"},
      keepalive:true,
      body:JSON.stringify(Object.assign(
        {tracking_id:t,pathname:location.pathname,
         referrer:document.referrer||undefined,session_id:sid()},
        utm()))});
  }
  send();
  window.addEventListener("popstate",send);
})();
</script>

Note: Replace YOUR-SITE-ID with the tracking ID from your Antlytics dashboard.

Verify installation

1. Visit your site in a browser.
2. Open your Antlytics dashboard → Overview.
3. Your visit should appear within a few seconds.

If data does not appear after a few minutes, check the troubleshooting guide.

Optional: First-party proxy
