Overview

The Google Analytics Data API (GA4) reads your analytics — reports and realtime data. Auth is OAuth 2.0 (unauthenticated requests return 404/400, verified).

Quick Start

Requires OAuth credentials — unauthenticated calls fail (verified 404):

curl "https://analyticsdata.googleapis.com/v1beta/properties/12345678:runReport" \
  -H "Authorization: Bearer YOUR_OAUTH_TOKEN"

Authentication

  • Create a Google Cloud project → enable Analytics Data API.
  • OAuth 2.0 or service account → bearer token.

Rate Limits & Notes

  • Free; Google Cloud quotas apply.
  • GA4 only (the old v3 universal analytics API is retired).

FAQ

Is Google Analytics free? The API is free within Cloud quotas.

Why 404 without auth? OAuth is required (verified) — configure credentials first.

What can I read? GA4 reports and realtime data.
