Twitch ID client of Application

i actually created the OAuth token using the guide, i used my virtual machine for create it, after, i used this code for see if the code work or not. (spoiler, don’t work…)

private static boolean validateOAuthToken() {
        try {
            OkHttpClient client = new OkHttpClient();

            // Crea una richiesta API che richieda l'autorizzazione del token
            Request request = new Request.Builder()
                    .url("https://api.twitch.tv/helix/users")
                    .header("Client-ID", "YOUR_TWITCH_CLIENT_ID") //i tried with my name and after with // ID client
                    .header("Authorization", "Bearer " + OAUTH_TOKEN)
                    .build();

            Response response = client.newCall(request).execute();

            int statusCode = response.code();
            return statusCode == 200;
        } catch (IOException e) {
            e.printStackTrace();
        }

        return false;
    }

EVERY time error 401…
