Best way to get list of files in Sharepoint whose permissions were updated

Question

Hi I am using MSFT Graph API to download files from Sharepoint. I am using the delta API to only get the list of files updated since my last run.

It looks like if only the permissions for a file are updated, then the file is not included in the delta feed. Is this correct? If yes, what is the best to get the list of files whose permissions were updated since my last run?

Answer 1

Yes, if only permissions for a file are updated, the file will not be included in the delta feed.

To track permission changes for a file, the best way is to use audit logs.

Go to Microsoft Purview portal -> Audit -> Search -> Sharing and access request activities -> Choose permission activities you want to track.
