# Google Analytics 4

**Canonical:** https://apis.io/providers/google-analytics-4/  
**Website:** https://developers.google.com/analytics  
**APIs profiled:** 3

Google Analytics 4 (GA4) is Google's event-based web and app analytics platform and the successor to Universal Analytics. Its developer surface has three distinct parts: the Analytics Data API (analyticsdata.googleapis.com) for running core, pivot, funnel and realtime reports and for exporting audiences; the Analytics Admin API (analyticsadmin.googleapis.com) for managing accounts, properties, data streams, custom dimensions and metrics, key events, access bindings and product links; and the Measurement Protocol (www.google-analytics.com/mp/collect) for sending server-side events directly into a property. Google publishes no OpenAPI for GA4 — the machine-readable contract is served as Google API Discovery documents on the API hosts themselves, alongside canonical protobuf service definitions in the googleapis repository. Authentication is Google OAuth 2.0 only for the Data and Admin APIs; the Measurement Protocol uses a per-stream shared secret.
