Seems “correct”

So you’ll need to add some error catching/testing the HTTP response/status code

For a user access token my PHP example might help

BarryCarlyon/twitch_misc/blob/master/authentication/user_access_generator/php/index.php#L38


    session_destroy();
    header('Location: /');

    exit;
} else if (isset($_GET['code']) && $_GET['code']) {
    // we have a code on the address line so lets parse and exchange

    // validate the state/nonce
    if (isset($_SESSION['nonce']) && isset($_GET['state']) && $_SESSION['nonce'] == $_GET['state']) {
        // lets exchange the code for an access token
        $ch = curl_init('https://id.twitch.tv/oauth2/token');
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, array(
            'client_id' => CLIENT_ID,
            'client_secret' => CLIENT_SECRET,
            'code' => $_GET['code'],
            'grant_type' => 'authorization_code',
            'redirect_uri' => REDIRECT_URI
        ));

is the relevant snippet for converting a code to an access token
