How to filter group members in Microsoft graph API?

Question

I was sure about after reading Microsoft document that I can filter the group members using OData Query Parameters because https://developer.microsoft.com/en-us/graph/docs/api-reference/v1.0/api/group_list_members

Request GET URL - https://graph.microsoft.com/v1.0/groups/{groupId}/members?filter= startswith(givenname,'V')

In above URL groupId is used from https://graph.microsoft.com/v1.0/groups

but when I try to get the result using Graph Explorer (https://developer.microsoft.com/en-us/graph/graph-explorer) using my work account login, it's not working.

Also I have tried to use this in SDK (I have implemented graph API in my code using Microsoft graph API SDK) and still got same error.

And gives below error -

{ "error": { "code": "Request_UnsupportedQuery", "message": "The specified filter to the reference property query is currently not supported.", "innerError": { "request-id": "96f3ffef-56f5-42e3-82f2-64813106b729", "date": "2018-02-13T10:59:39" } } }

Is this because "members" is not a resource type ? so it does not have properties and so we can not filter this result ?

If so then is there any other way we can get filtered group members ?

Also posted issue on Github - https://github.com/microsoftgraph/microsoft-graph-docs/issues/2239

I believe it is because /members returns a list of directoryObjects. Even though the user resource inherits from directoryObject, you can't filter on givenName here. You would have to do client-side filtering to search for specific members. — RasmusW
Per my testing, both Microsoft graph and Azure AD graph could not support the filter query against group members as you mentioned. You may retrieve all the members under a specific group and filter them in your client as RasmusW commented. Or you could add your feature request to Microsoft Graph team. — Bruce Chen
@BruceChen thanks. Microsoft documentation should be corrected then that we can not filter group members. — vishwajeetrkale
I've created a UserVoice suggestion for this: officespdev.uservoice.com/forums/… — Thomas

Add ConsistencyLevel: eventual to Your request header (should work for v1.0 and beta as well)
