properties Property
This property can be present both in the root request object and also in the retDailyData object. In both cases, this property is optional. If this property is not present in the root object, the only current property that is returned is the client ID. Similarly, if this property is not present in the retDailyData object, the daily data would contain only the dates on which each client was active without any further details about what the value of client data properties was on each day.
