EndDate: Date on which the campaign will stop running. On insert, the end date must be today or a future date. The end date must be later than or be the same as the start date. If, for example, you set 6/25/2015 as both the start and end dates, the effective campaign run date is just that day only, 6/25/2015. The hours, minutes, and seconds of the end date should not be set, as doing so will result in an error. This is a required field.
