Webgriffe MonetaWeb 2.0 PHP library

This library provides a complete integration for the XML Hosted 3DSecure protocol of Setefi MonetaWeb 2.0 payment gateway. It was developed following the technical documentation provided by Setefi released in July 2017.

Installation

In order to use this library, first of all import it using composer:

Usage

Payment initialization

You can generate a payment initialization URL using the GatewayClient class:

$gatewayClient = new Webgriffe\LibMonetaWebDue\Api\GatewayClient();
$getPaymentPageInfo = $gatewayClient->getPaymentPageInfo(
    'https://ecommerce.keyclient.it/ecomm/ecomm/DispatcherServlet',
    '99999999',
    '99999999',
    1428.7,
    'EUR',
    'ITA',
    'http://www.merchant.it/notify/',
    'http://www.merchant.it/error/',
    'TRCK0001',
    'Descrizione',
    'Nome Cognome',
    '[email protected]',
    'Campo Personalizzabile'
);

The getPaymentPageInfo method returns a GatewayPageInfo value object that encapsulates 3 values:

• Payment ID, unique ID of the payment session
• Security Token, an hash that should be compared to the one returned in the response of the notify request (server-to-server notification, of which we talk below)
• Hosted Page URL, the URL to which the user must be redirected in order to perform the payment

Server to server notification

Once that you redirected the user to the Hosted Page URL a server-to-server notification will be perfomed by MonetaWebDue to one of the 2 urls that you specified when you called getPaymentPageInfo. In the example of the payment initialization the user will be redirected to http://www.merchant.it/notify/ in case of successful operation and to http://www.merchant.it/error/ otherwise.

You can handle this request by using the handleNotify method of the GatewayClient class:

$gatewayClient = new Webgriffe\LibMonetaWebDue\Api\GatewayClient();
...
// $psrRequest must be an instance of an object that implements the \Psr\Http\Message\RequestInterface
$paymentResult = $gatewayClient->handleNotify($psrRequest);

The result of the handleNotify method could be a PaymentResultInfo object or a PaymentResultErrorInfo:

• The former object is returned when the notify request comunicates that the payment was handled successfully (this does not means that the payment was successful!). The properties of this object are mapped 1to1 with the successful notify response parameters, so refer to the payment gateway's integration documentation for more details about them.
• Instead, the latter object is returned when the notify request comunicates an error. This means that something went unexpectedly wrong during the payment. This has nothing to do with, for example, a "canceled" order: cases like this are not unexpected and so they generates a PaymentResultInfo object (as explained above). Even the properties of this object are mapped 1to1 with the parameters of the "faulty notify response", so refer to the payment gateway's integration documentation for more details about them.

The Security Token is a value that is comunicated by Setefi both in the payment initialization response and the server to server notification. You should compare them to be ensure the integrity of the payment. In order to do this, the GatewayClient class has a method called verifySecurityToken that accepts the initialization's security token and the payment result info (returned by the handle notify) as parameters and returns a boolean:

$gatewayClient = new Webgriffe\LibMonetaWebDue\Api\GatewayClient();
...
$match = $gatewayClient->verifySecurityToken($storedSecurityToken, $paymentResult);

So an example of a real implementation for the server to server notification could be this:

$gatewayClient = new Webgriffe\LibMonetaWebDue\Api\GatewayClient();
...
$paymentResult = $gatewayClient->handleNotify($psrRequest);
if ($paymentResult instanceof PaymentResultErrorInfo) {
    ..
} else {
    /** @var PaymentResultInfo $paymentResult */
    if (!$paymentResult->isCanceled()) { // the security token is not returned if the payment was canceled
        if (!$gatewayClient->verifySecurityToken($storedSecurityToken, $paymentResult)) {
            // error
            ..
        }
    }
    ..
}
