If you already have a Credentials object then you can refresh it like so:

if refresh:
    import google_auth_httplib2
    # credentials instanceof google.oauth2.credentials.Credentials
    credentials.refresh(google_auth_httplib2.Request(httplib2.Http()))

I had created the Credentials object from an old token JSON file like so:

    credentials = google.oauth2.credentials.Credentials(
        token=token_json['access_token'],
        refresh_token=token_json['refresh_token'],
        id_token=token_json['id_token'],
        token_uri=token_json['token_uri'],
        client_id=token_json['client_id'],
        client_secret=token_json['client_secret'],
        scopes=token_json['scopes'])

In this way I was able to adapt some old oauth2client code.
