message

A message that describes the notification. The notification message is the result of evaluating the Geotrigger.messageExpression for the specific objects that triggered this notification. The message could be a hard-coded string or use attributes from an area of interest that was entered to display a custom message.

For example, with a FenceGeotrigger, setting the Geotrigger.messageExpression property to:

"You have entered " + $fencefeature.area_name

would return the GeotriggerNotificationInfo.message "You have entered Area A", where "area_name" is an attribute field on the FenceGeotriggerNotificationInfo.fenceGeoElement.

You can use this message to alert the user directly or in other business logic in your app.
