Recognia Event Ids are unique but not guaranteed to stay the same for a specific event. I.e. an event could have id 12 one day and id 37 the next day but still be the same event. Event Ids change when there has been a price correction or the event recognition algorithms have been updated.
This API command enables you to verify an Event Id as still being valid. You may wish to use this command when you display a list of events with links to a chart or more detailed information. Your code on the new screen would check to make sure the Event Id is valid and if so then display the screen.
