Specifies the start date and time for which notification information will be retrieved. StartTime is optional. If no StartTime is specified, the default value of 24 hours prior to the call time is used. If no StartTime is specified or if an invalid StartTime is specified, date range errors are returned in the response. For a StartTime to be valid, it must be no more than 72 hours before the time of the call, it cannot be more recent than the EndTime, and it cannot be later than the time of the call. If an invalid StartTime is specified, the default value is used.

Field Index to learn which calls use StartTime.
