Hello i need to list all modified / deleted / canceled occurrences of a event.

I know the Request => GET /users/{id | userPrincipalName}/calendar/events/{id}/instances?startDateTime={start_datetime}&endDateTime={end_datetime}

I understand that it is nessery to have a endDateTime for a open RepeatRange with no EndDate when i want to list all occurrences.
But even with a specified Range modified (or modified and then deleted / canceled) occurrences can be have their occurrence-Date befor or after the RepeatRange-Definition.
In EWS it was simple to get a list with a modified occurences and deleted occurrences.
How can i archieve this with graph api?

Do i have to look via a CalenderView into it and use Search-Params for all occurrences from the Master?
Is there no way to get i simple list(s) with informations about modified and deleted/canceled occurrences?

    Hi @ASCII

    You can call the /delta endpoint to track event changes (add/remove/update). 

    GET https://graph.microsoft.com/v1.0/users/{id | userPrincipalName}/calendarView/delta?startdatetime={start_datetime}&enddatetime={end_datetime}  
Prefer: odata.maxpagesize=2
