Hello, where can I put this code in my forum?

<!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=UA-73772477-1"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'UA-73772477-1');
</script>

 

 

 

Take a look in System->Site Features->Integrations, which has the locations you are looking for.

Hello, thank you very much!
