Saferpay API, an unofficial implementation

installation

with buzz

"payment/saferpay": "~3.0"
"payment/httpclient-buzz": "~1.2"

with guzzle

"payment/saferpay": "~3.0"
"payment/httpclient-guzzle": "~1.1"

a simple implementation

uses default (with buzz client)

use Payment\HttpClient\BuzzClient;
use Payment\Saferpay\Data\PayInitParameter;

creating a saferpay instance

use Payment\Saferpay\Saferpay;

$saferpay = new Saferpay;

set httpclient (with buzz)

$saferpay->setHttpClient(new BuzzClient());

implementation

$amount = 1200;
$currency = 'CHF';

if (getParam('status') == 'success') {
    $payConfirmParameter = $saferpay->verifyPayConfirm(getParam('DATA'), getParam('SIGNATURE'));
    if ($payConfirmParameter->get('AMOUNT') == $amount && $payConfirmParameter->get('CURRENCY') == $currency) {
        $saferpay->payCompleteV2($payConfirmParameter, 'Settlement');
        echo 'payment success!';
    } else {
        $saferpay->payCompleteV2($payConfirmParameter, 'Cancel');
        echo 'payment failed!';
    }
} else {
    $payInitParameter = new PayInitParameter();
    $payInitParameter->setAccountid(PayInitParameter::SAFERPAYTESTACCOUNT_ACCOUNTID);
    $payInitParameter->setAmount($amount);
    $payInitParameter->setCurrency($currency);
    $payInitParameter->setDescription(sprintf('Ordernumber: %s', '000001'));
    $payInitParameter->setSuccesslink(requestUrl() . '?status=success');
    $payInitParameter->setFaillink(requestUrl() . '?status=fail');
    $payInitParameter->setBacklink(requestUrl() . '?status=back');
    $payInitParameter->setDelivery('no'); // hide address form
    header('Location: ' . $saferpay->createPayInit($payInitParameter) , 302);
}

a billpay implemention (works only with providerset, use it standalone)

uses billpay (with buzz client)

we define some helpers (plain php)

function requestUrl()
{
    $protocol = strtolower(substr($_SERVER['SERVER_PROTOCOL'], 0, strpos($_SERVER['SERVER_PROTOCOL'], '/')));
    return $protocol . '://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
}

function getParam($key, $default = null)
{
    return array_key_exists($key, $_REQUEST) ? $_REQUEST[$key] : $default;
}
