Due to the unique structure of Apple HealthKit heart rate data, only one biometrics measurement record with heart rate data will be created in the Validic API per user per day for Apple Health using the Validic Mobile library. This record will contain minimum, maximum, and average heart rate may contain min_heart_rate, max_heart_rate, avg_heart_rate, and pulse values calculated from all the readings taken throughout that day from any device that writes heart rate data to HealthKit. The data will be available in the expanded data of the biometrics record.
