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.

https://docs.microsoft.com/en-us/graph/api/resources/site?view=graph-rest-1.0

https://docs.microsoft.com/en-us/graph/api/resources/site?view=graph-rest-beta

Answer 2

It seems that now Owners and Members can be accessed via the Graph API. See this post.

Site groups now appear under https://graph.microsoft.com/v1.0/groups/, and you can access owners and members with

• https://graph.microsoft.com/v1.0/groups/{groupId}/owners
• https://graph.microsoft.com/v1.0/groups/{groupId}/members

respectively

However, I still do not see a way to access visitors

Alternatively, per this post, it seems that you can query a site's User Information List, and then see the ContentType: Person results to find who it has been shared with.

Answer 3

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).

Source: Working with SharePoint sites in Microsoft Graph.

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.
