Google Analytics 4

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.

Google Analytics 4 publishes 3 APIs on the APIs.io network: Accounts API, Account Summaries API, and Properties API. Tagged areas include Analytics, Data Collection, Marketing, Measurements, and Mobile Analytics.

The Google Analytics 4 catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Google Analytics 4’s developer surface includes authentication, changelog, sandbox, documentation, API reference, getting-started guide, developer console, and 42 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/google-analytics-4: open an issue to ask a question, or submit a pull request to add artifacts.
