How to get sharepoint site group name using Graph API?

Hello Andrea Quarta,

Thank you for contacting Microsoft Support!

Upon reviewing the Microsoft Graph API documentation, it appears that there isn’t a specific endpoint available to retrieve SharePoint Group Owners, members or their visitors at this time. However, if your goal is to obtain a comprehensive list of users and groups associated with a SharePoint site, you may perform a query on the “User Information List” as follows:

GET https://graph.microsoft.com/v1.0/sites/{siteid}/lists/User Information List/items?expand=fields

Hope this helps.

As Hitesh Pachipulusu said, there is no Graph API to retrieve SharePoint groups.

You could use Graph API GET https://graph.microsoft.com/v1.0/sites/{siteid}/lists/User Information List/items?expand=fields to list users and groups in the user information list.

Note: Only site collection administrator can access user information list. Make sure you are site collection administrator then run Graph API.

In another way, you could use PowerShell to get all SharePoint groups.
