Use Google Tag Manager

The Umami tracker can be installed using Google Tag Manager.

Normally, you would install the Umami tracker by using the following code:

<script
  defer
  src="http://mywebsite.com/script.js"
  data-website-id="94db1cb1-74f4-4a40-ad6c-962362670409"
></script>

However, Google Tag Manager will strip the attributes from the tracker. So you need to using the following code instead:

<script>
  (function () {
  var el = document.createElement('script');
  el.setAttribute('src', 'http://mywebsite.com/script.js');
  el.setAttribute('data-website-id', '94db1cb1-74f4-4a40-ad6c-962362670409');
  document.body.appendChild(el);
})();
</script>
