UMID in UID

Our library enables user identification in Google Analytics through the use of umid as uid or user_id. This functionality allows for the creation of historical user reports that do not expire, regardless of the user's login status. To implement this feature, it is essential to insert a specific script into the HTML code before the Google Tag Manager installation snippet.

<script>  
  (function(){
  var script = document.createElement("script")
  script.type = "text/javascript"
  script.src = "https://fc.[your-domain]/teavaroUmidSessionDataLayerManager.js"
  document.head.appendChild(script)
  })();
</script>

<!-- Google Tag Manager -->
<script>
...
</script>
<!-- End Google Tag Manager -->

An additional configuration is needed in the GTM container to allow using user_id in Google Analytics reports.

First, you must create a new variable to read the user_id from the dataLayer. In the left sidebar menu, go to Variables → User-Defined Variables and add a new one with type Data Layer Variable. The Data Layer Variable Name field must be user_id. See the following example:

Now, in the Tags section, this variable must be added as a parameter to the Google Analytics integration tag. The tag type is usually Google Tag, and every tag with the type Google Analytics: GA4 Event. See the following example:

The Configuration parameter must be user_id and the Value is the previously created Data Layer Variable. This is another example of this implementation in Google Analytics: GA4 Event Tag:
