For those who cannot use session ensure you use a stateless() state and then do something like this

    Socialite::driver('google')->with([
        'state' => http_build_query([
            'utm_source' => $request->query('utm_source') ?? 'none',
            'utm_medium' => $request->query('utm_medium') ?? 'none',
        ])
    ])->stateless()->redirect();
