        curl_close($ch);
    }
}

위 API를 이용해 Sign-Up 기능을 구현한 코드는 아래오 같다.

<?php
require_once('./Payoneer.Api.php');

$payee_id = trim($_POST['payee_id']);

$payoneer = new Payoneer(PAYONEER_USERNAME, PAYONEER_API_PASSWORD, PAYONEER_PARTNER_ID, PAYONEER_SANDBOX);

$request = array(
    'p4'  => $payee_id,
    'p6'  => 'http://example.com/payoneer/payoneer.php',
    'p8'  => 5,
    'p10' => 'True'
);

$result = $payoneer->getToken($request);

$error = '';
$token = '';

if(isset($result['Token'])) {
    $token = $result['Token'];
} else {
    $error = '['.$result['Code'].'] '.$result['Description'];
}

die(json_encode(array('error' => $error, 'token' => $token)));
