REST API to check User Permission

Posted by Paul on October 17, 2015


In this article we can explore the REST API to check User Permission for a Group.

Scenario

You are working in a client-side script SharePoint App. You need to check whether the current user belongs to the Approvers group. The twist is that the current user is added to an AD Group and in turn the AD Group was added to SharePoint group.

Solution: Following is the REST code to get the result.

http://sharepoint/_api/web/sitegroups/getbyname(‘Approvers’)/CanCurrentUserViewMembership

Following is the result.

You can try REST code in browser address bar itself. Later you can wrap a JavaScript or AngularJS around it to attain programmatic checking.

If I enter an invalid group name, the result will be different.

http://sharepoint/_api/web/sitegroups/getbyname(‘InvalidGroup’)/CanCurrentUserViewMembership

We can also check Site Collection & Sub Site permission groups using the same way.

Pre-Conditions

The above code is checking does the user have View Membership permission. In order to make this work we need to configure the following group property as true.

By default this property will be true.
