I am currently working on supporting Service update notifications in the existing webhook scripts. I have found that these notification events don't support the macro {EVENT.UPDATE.STATUS}. We use this macro to determine the type of event - Update or Problem for Trigger-based notifications. Service update notifications are very similar to them, and we expected to use the macro {EVENT.UPDATE.STATUS} for them to determine the notification type. Especially since other macros like {EVENT.UPDATE.DATE} or {EVENT.UPDATE.SEVERITY} are supported by both types of events.
 
Was it intentionally designed that Service update notifications don't support the macro {EVENT.UPDATE.STATUS}? Can its support be added? If not, how can we determine the type of notifications (Update or Problem) for Service update notifications events?
