Query Google Analytics 4 via curl + jq. The user's OAuth bearer token is in
$GOOGLE_ANALYTICS_TOKEN (scope analytics.readonly); every call needs
Authorization: Bearer $GOOGLE_ANALYTICS_TOKEN. Two APIs: the Admin API
(analyticsadmin.googleapis.com/v1beta) to discover properties, and the Data
API (analyticsdata.googleapis.com/v1beta) to run reports.
Failures are {"error":{"code","message","status"}} — show verbatim. 401 =
re-install.
AUTH="Authorization: Bearer $GOOGLE_ANALYTICS_TOKEN"
# List the GA4 properties the user can access (via their account summaries)
curl -sS -H "$AUTH" "https://analyticsadmin.googleapis.com/v1beta/accountSummaries" \
| jq '.accountSummaries[]?.propertySummaries[]? | {property, displayName}'
property looks like properties/123456789 — the number is the PROPERTY_ID.

Swap dimensions/metrics for other reports: sessionDefaultChannelGroup +
sessions (acquisition), country + activeUsers (geo), eventName +
eventCount / conversions (events). Dates accept NdaysAgo, today,
yesterday, or YYYY-MM-DD.

Gotchas
- This is GA4 only (Data API v1). Old Universal Analytics (UA) is shut down —
don't use the legacy
analytics/v3endpoints. - Valid dimension/metric API names matter (
screenPageViews, not "Pageviews"). If a name 400s, it's the wrong API id — check the GA4 dimensions & metrics list. - Reports are capped by
limit(default 10k rows); page withoffset.
