title: How to filter group members in Microsoft graph API?
body: <p>I was sure about after reading Microsoft document that I can filter the group members using OData Query Parameters because <a href="https://developer.microsoft.com/en-us/graph/docs/api-reference/v1.0/api/group_list_members" rel="noreferrer">https://developer.microsoft.com/en-us/graph/docs/api-reference/v1.0/api/group_list_members</a></p>
  
  <p>Request GET URL - <a href="https://graph.microsoft.com/v1.0/groups/" rel="noreferrer">https://graph.microsoft.com/v1.0/groups/</a>{groupId}/members?filter= startswith(givenname,'V')</p>
  
  <p>In above URL groupId is used from <a href="https://graph.microsoft.com/v1.0/groups" rel="noreferrer">https://graph.microsoft.com/v1.0/groups</a></p>
  
  <p>but when I try to get the result using Graph Explorer (<a href="https://developer.microsoft.com/en-us/graph/graph-explorer" rel="noreferrer">https://developer.microsoft.com/en-us/graph/graph-explorer</a>) using my work account login, it's not working.</p>
  
  <p>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.</p>
  
  <p>And gives below error -</p>
  
  <p>{
      "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"
          }
      }
  }</p>
  
  <p>Is this because "members" is not a resource type ? so it does not have properties and so we can not filter this result ?</p>
  
  <p>If so then is there any other way we can get filtered group members ?</p>
  
  <p>Also posted issue on Github - <a href="https://github.com/microsoftgraph/microsoft-graph-docs/issues/2239" rel="noreferrer">https://github.com/microsoftgraph/microsoft-graph-docs/issues/2239</a></p>
