Pulling a user's group membership list in Google Apps

Question

I'm converting my application over to the directory API and am trying to find a way to pull a user's group membership in google using .NET.

Looking at the API page: Google Apps API

I see "Retrieve a Group's Member" that requires both a group and a member's key. I can't find this call in the service.Groups functions. I also looked at the service.Membership functions and I'm not finding anything.

Where is the API that pulls a single user's group membership?

Update:

This is the call I'm attempting to use:

        try
        {
            GroupsResource.ListRequest groups = service.Groups.List();
            groups.Domain = "appDomain.com";
            groups.Customer = strGoogleCusID;
            groups.MaxResults = 100;
            groups.PageToken = "";
            groups.UserKey = "User@appDomain.com";
            var list = groups.Execute();
        }
        catch (Google.GoogleApiException ex)
        {
        }

But it returns bad request. I can use this function to return all groups in a domain, but if I specify the UserKey I get 400 Bad Request.

You can use the Groups -> list API where a userKey can be specified. It returns all the groups the user is a memberOf. Here's the link - https://developers.google.com/admin-sdk/directory/v1/reference/groups/list
