Get Sharepoint library permissions

Question

I am looking to see how I can get a list of all users, and groups, and users within groups, that have permissions to Libraries within Sharepoint.

I am trying to use MS Graph, but I am open to using the graph or the sharepoint rest api.

Any help would be appreciated!

Hi @Rick Doll ,

Currently using Graph API, you can either get site permission and get drive item permissions, fetching permissions for list or library is not supported. You can upvote this feature request for list permissions user voice.

You can get subsite using GET /sites/domain.sharepoint.com:/{sitecoll}/{subsite}
Get all lists from a subsite GET /sites/domain.sharepoint.com:/{sitecoll}/{subsite}:/lists,
Drives GET /sites/domain.sharepoint.com:/{sitecoll}/{subsite}:/drives

Using SharePoint REST APIs you can get permissions for a site, list, library, item as well.

https://domain.sharepoint.com/sites/{sitecoll}/{subsite}/_api/web/lists/GetByTitle('{listTitle}')/RoleAssignments?$expand=Member  

Refrences:

• Graph Site Id
• SharePoint REST

Hope this helps.

We are using this API :
https://graph.microsoft.com/v1.0/sites/<host>.sharepoint.com,<siteid>/lists/<listid>/items?expand=fields(select=id,Title)&select=id&$filter=fields/Modified ge '2022-04-15T09:29:37.3541196Z' (this operation in the doc: listitem-list).

But we also tried to call this API https://graph.microsoft.com/v1.0/sites/<host>.sharepoint.com,<siteid>/permissions and we have an error telling that the operation is not supported... But it was working in the past (this operation in the doc: site-list-permissions).

In fact, the API call was the right one, but there was an error in the Graph API after a recent deployment made by Microsoft, as explained in this post: the-34sitesselected34-permission-is-not-working-an.html
