SECURITY WARNING

Never keep your private and public keys in publicly accessible folder. Instead place keys under root folder (usually public_html or www).

If you store keys as strings in database, then they should be accessible only over HTTPS protocol.

Payment

<?php
    require __DIR__ . '/vendor/autoload.php';

    use RKD\Banklink;

    // Init protocol
    $protocol = new Banklink\Protocol\IPizza(
        'uid100010', // seller ID (VK_SND_ID)
        __DIR__ . '/../keys/seb_user_key.pem', // private key
        '', // private key password, leave empty, if not needed
        __DIR__ . '/../keys/seb_bank_cert.pem', // public key
        'http://localhost/banklink/SEB.php' // return url
    );

    // Init banklink
    $seb = new Banklink\EE\SEB($protocol);

    // Set payment data and get payment request object
    // orderId, sum, message, language
    $request = $seb->getPaymentRequest(123453, 150, 'Test makse', 'EST');

    // You can also add custom request data and/or override request data
    // Optional
    $request = $seb->getPaymentRequest(123453, 150, 'Test makse', 'EST', 'EUR', [
        'VK_REF' => 'my_custom_reference_number', // Override reference number
        'INAPP' => true // Pocopay specific example
    ]);
?>

<form method="POST" action="<?php echo $request->getRequestUrl(); ?>">
  <?php echo $request->getRequestInputs(); ?>
  <input type="submit" value="Pay with SEB!" />
</form>

<?php
    require __DIR__ . '/vendor/autoload.php';

    use RKD\Banklink;

        __DIR__ . '/../keys/seb_user_key.pem', // private key
        '', // private key password, leave empty, if not needed
        __DIR__ . '/../keys/seb_bank_cert.pem', // public key
        'http://localhost/banklink/SEB.php' // return url
    );
