SharePoint Online sitegroups REST query in graph API

Question

I have a question regarding quering site groups via REST Graph API instead of SharePoint REST API. Currently I need to query SharePoint REST API to find implicit groups (*Visitors, *Members, *Owners) for each site in order to find users that are members of those groups (those groups are not present in groups Graph API). To achieve this I am using two queries. First:

https://{site_url}/sites/{ site name}/_api/Web/SiteGroups

to obtain list of implicit groups with type ids, and then:

https://{site_url}/sites/{ site name}/_api/Web/SiteGroups/GetById({id})/Users

to obtain list of users in one specific group obtained from first query.

So the question is: Are any equivalents to those two queries above in REST Graph API or I need still to obtain those information from SharePoint REST API?

Answer 1

Looking at the documentation for the Sites endpoint (both v1.0 and beta), it does not appear that you can get SharePoint Permission Groups or their members from the Graph.

Answer 2

As per my understanding currently Microsoft Graph does not support working with SharePoint groups and we can only work with Sites, Lists and ListItems using Microsoft Graph (correct me if I am wrong).

Workaround:

1. Go with traditional SharePoint REST APIs as you are already using.
2. Use PnPJS library to get SharePoint Site groups and Group members easily.
