Charts and Headers

Charts and headers use flat reporting query parameters: GET https://data.goodmetrics.io/{gmID}/events/{resource}?start={start}&end={end}.

Overview chart

Endpoint	Description
GET /{gmID}/events/charts/overview	Time-series analytics for one chart metric.

Chart requests support date range, filter, type, and interval query parameters.

Supported intervals are hour, day, week, and month.

Session-centric chart types include unique_visitors, page_views, visits, page_views_per_visit, bounce_rate, and avg_visit_duration.

Event-centric chart types include avg_time_on_page, visits, pageviews, and unique_visitors. A request becomes event-centric when it filters by page or subdomain.

Headers

Header endpoints return high-level summary metrics for the selected report area.

Endpoint	Description
GET /{gmID}/events/headers/acquisition	Acquisition summary metrics.
GET /{gmID}/events/headers/audience	Audience summary metrics.
GET /{gmID}/events/headers/events	Custom event summary metrics.
GET /{gmID}/events/headers/pages	Page summary metrics.

Use the same flat query parameters as table endpoints:
