Yes, you can use Google Analytics 4 (GA4) with Google Tag Manager (GTM).
Google Tag Manager is a free tool that allows you to add and manage various tracking and marketing tags on your website or mobile app, such as those for Google Analytics, Facebook Pixel, and more, without requiring you to modify the source code of your website or app.
By using GTM, you can easily add the GA4 tracking code to your website or mobile app, and you’ll be able to use GTM’s built-in triggers and variables to fire events and collect data in GA4. GTM also allows you to manage and preview your GA4 events in real-time and also allows you to test and debug your GA4 implementation before going live.
Additionally, GTM provides a way to deploy GA4 features, such as App+Web properties and User ID feature, without requiring any changes to the website or app code.
It is important to note that to use GA4 with GTM, you need to create a GA4 property in your Google Analytics account and link it to GTM. You will also need to create a GA4 configuration tag in GTM, which is used to set up GA4 tracking on your website or mobile app.
