Use this to retrieve Google Analytics 4 data for one property: users, sessions, views, engagement, events, key events, revenue and any other metric, optionally broken down by dimensions such as date, channel, source/medium, landing page, page path, country, device or event name, and narrowed with filters (for example sessions from Organic Search to pages starting with '/blog/'). With no metrics it reports activeUsers, sessions and screenPageViews; with no dates it covers the last 28 days ending yesterday. Dates are in the property's time zone. Returns totals and up to 100 rows per call (default 20); page through with the returned cursor. Rates such as engagementRate are fractions. Google may withhold small values (thresholding) or sample large reports; the result says so. Figures are observed values and do not identify causes. Use list_fields to find custom dimension and metric names. Read-only.
