What kind of activities which we receive from onedrive API on editing of a ppt file. Why it doesnt show 'FileModified' Operation? I am using the API (subscription URI ) https://manage.office.com/api/v1.0/{{TenantID}}/activity/feed/subscriptions/content?contentType=Audit.SharePoint&startTime=2021-03-30T10:46:22&endTime=2021-03-30T10:47:27 to detect the changes in my drive.
From which we get the results in
https://manage.office.com/api/v1.0/f43eddbb-b83c-46b3-9a9d-722e890a5fdb/activity/feed/audit/20210330104635032000020$20210330104720587000490$audit_sharepoint$Audit_SharePoint$na0022
I do not get 'FileModified' operation on my results from the ppt file changes. What are the obvious ways to know if the file in my onedrive has changed through API polling?
