Start date of requested transaction list.
This is a string representing the date at which to start listing transactions on the statement. Use this property and EndDate to constrain the list of transactions retrieved when calling GetStatement. When provided in the request, StartDate value will be echoed in the server's response.
All input dates should be entered in the format specified by DateFormat. For example, if the DateFormat is set to "MM/dd/yyyy hh:mm:ss" (default value), an input date should look like: 09/30/2009 12:00:00 AM.
This format specifies also how the returned dates are going to get parsed.
Note: This property is optional and can be specified when IncludeTransactions property is set to True.
