Question

Hi there

In SharePoint and OneDrive, is there any API that can get a list of files/folders shared with external users and expiry dates when external users' access will expire?

Thank you.

Answer 1

There is, you can query the /permissions facet on each file/folder. Here's a sample script I wrote a while back: https://practical365.com/reporting-on-onedrive-for-business-shared-files/
The above is using the Graph API, you can of course use CSOM or the PowerShell PnP module as alternative.
There's also a built-in report you can generate via the UI: https://learn.microsoft.com/en-us/sharepoint/sharing-reports

Hi @frob ,
You can create a sharelink by following graph api

POST /drives/{driveId}/items/{itemId}/createLink  
POST /groups/{groupId}/drive/items/{itemId}/createLink  
POST /me/drive/items/{itemId}/createLink  
POST /sites/{siteId}/drive/items/{itemId}/createLink  
POST /users/{userId}/drive/items/{itemId}/createLink  

https://learn.microsoft.com/en-us/graph/api/driveitem-createlink?view=graph-rest-1.0&tabs=http

You can also grant permissions by following url

POST /shares/{encoded-sharing-url}/permission/grant
