Read from Google’s documentation on 2026-10-17 · discovery document revision 20261014 · Google’s data-types page last updated 2026-10-06

Daily Heart Rate Zones (daily-heart-rate-zones) is a Daily data type in the Google Health API. Google's data-types table lists list and reconcile for it under the .health_metrics_and_measurements.readonly and .health_metrics_and_measurements.writeonly scopes. The table marks it with webhook support. Google's Fitbit migration table names no Fitbit Web API predecessor for it.

How do you aggregate daily-heart-rate-zones data with the Google Health API?

Not with rollUp or dailyRollUp, going by Google's data-types table: it lists only list and reconcile for daily-heart-rate-zones. Read the data points with list (or reconcile, where listed) and compute any summary yourself.
