  }


  public function request($endpoint, $method = 'GET', $body = FALSE) {
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $this->base_url . $endpoint);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

//$payment = $magento->getPaymentMethods($cart);
//var_dump($payment);

$ordered = $magento->placeOrder($cart, 'cashondelivery');
echo "\nordered:\n";
var_dump($ordered)

;

Can any one help me on this problem ? Any references or suggestions are highly appreciated. Thanks in advance.

All seems good with your code I have tried it and it's working .Check with your instance custom modules and access token.
