How can I track custom events in GA4 using Google Tag Manager?

Asked on Nov 14, 2025

Answer

To track custom events in GA4 using Google Tag Manager, you'll need to set up a new tag in GTM that sends event data to your GA4 property. This involves configuring a GA4 Event tag and defining the event parameters you want to track.

<!-- BEGIN COPY / PASTE -->
    1. Go to Google Tag Manager and click on "Tags" in the left-hand menu.
    2. Click "New" and select "Tag Configuration".
    3. Choose "Google Analytics: GA4 Event" as the tag type.
    4. Enter your GA4 Measurement ID in the "Configuration Tag" field.
    5. Name your event in the "Event Name" field.
    6. Add any parameters you want to track under "Event Parameters".
    7. Set up a trigger that defines when this event should be sent.
    8. Save your tag and publish the container.
    <!-- END COPY / PASTE -->

Additional Comment:

Ensure your GA4 Measurement ID is correctly set up in the GTM container.
Test your tag using GTM's Preview mode to verify that events are being sent correctly.
Check the "Realtime" report in GA4 to confirm that your custom events are being tracked.
Use descriptive event names and parameters to make analysis easier in GA4.
