How to add api_secret to GA4 events using SGTM?
Hello @Marcus_Larsen,
To add an api_secret to your GA4 events in server-side GTM for offline tracking, you have to configure the Google Analytics: GA4 tag to include it as a request parameter. This is required because offline events typically use the GA4 Measurement Protocol, which mandates an API secret for authentication. We also recommend referring to the Measurement Protocol developer documentation linked here.
