This is a Proxy Integration for GA4. This destination runs on Freshpaint's servers, but emulates a native installation of GA4. That means the integration behaves the same as if you did a native installation of GA4, but the data first flows through Freshpaint before it's sent to GA4. See our docs on proxy integrations for more information.
Google Analytics 4 is an analytics service that enables you to measure traffic and engagement across your websites and apps.
After sending Freshpaint data to Google Analytics 4, you'll be able to analyze the data in order to identify trends and patterns in how visitors engage with your website(s).
