Answer

Setting up a custom event in Google Tag Manager (GTM) for GA4 involves creating a new tag and configuring it to send event data to your GA4 property. This process allows you to track specific interactions on your website that are not automatically captured by GA4.

<!-- BEGIN COPY / PASTE -->
    1. Open Google Tag Manager and click on "Tags" in the left-hand menu.
    2. Click "New" to create a new tag.
    3. Choose "Tag Configuration" and select "Google Analytics: GA4 Event".
    4. Enter your GA4 Measurement ID in the "Configuration Tag" field.
    5. Provide a name for the event in the "Event Name" field.
    6. Add any necessary event parameters by clicking "Add Row" under "Event Parameters".
    7. Set up a trigger for when this event should be fired (e.g., button click).
    8. Save the tag and publish your container.
    <!-- END COPY / PASTE -->

Additional Comment:

Ensure that your GA4 Measurement ID is correctly set up in GTM to send data to the right property.
Use descriptive event names and parameters to make reporting in GA4 more intuitive.
Test the tag in GTM's Preview mode before publishing to ensure it fires correctly.
Consider using Google Analytics Debugger to verify event data in GA4.
