Transbank SOAP

Set of utilities to validate and process the XMLs of the SOAP services of Transbank

This library IS NOT an implementation of Webpay Webservices.

The current implementation of the utilities used in the Transbank Webservice SOAP libraries (mid 2018 and before) are modified classes of Rob Richards' libraries (wsse-php and xmlseclibs), possibly because these classes have private and unprotected methods and properties, therefore they cannot be inherited in order to use the properties.

This library uses a different approach after analyzing such implementation, isolating specific functionalities that must be applied to XML to build a valid request.

Installation

composer require luisurrutia/transbank-soap

Getting started

First you must import this library by making use of the autoloaderthat provides composer or by making individual require or require_once (although perhaps we should kill you if you do the last)

Build the request

Assuming you have a class that inherits from SoapClient, you must implement the __doRequestmethod and within it, you must make use of LuisUrrutia\TransbankSoap\Process to build the XML of the request.

PRIVATE_KEY should be a path of your private key or your private key itself

CERTIFICATE should be a path of your certificate or your certificate itself

<?php
namespace MYPACKAGE\Transbank;

use SoapClient;
use DOMDocument;
use LuisUrrutia\TransbankSoap\Process;


class TransbankSoap extends SoapClient
{
    public function __doRequest($request, $location, $saction, $version, $one_way = null)
    {
        $process = new Process($request);
        $process->sign(PRIVATE_KEY);
        $process->addIssuer(CERTIFICATE);
        $signedRequest = $process->getXML();

        $retVal = parent::__doRequest(
            $signedRequest,
            $location,
            $saction,
            $version,
            $one_way
        );

        $doc = new DOMDocument();
        $doc->loadXML($retVal);
        return $doc->saveXML();
    }
}

Validation of Response

You must get the response from your SOAP client and use LuisUrrutia\TransbankSoap\Validation

$this->soapClient should be an instance of your SoapClient

TBK_CERTIFICATE should be the certificate provided by Transbank

<?php
namespace MYPACKAGE\Transbank;

use LuisUrrutia\TransbankSoap\Validation;

$response = $this->soapClient->__getLastResponse();

$soapValidation = new Validation($response, TBK_CERTIFICATE);

if (!$soapValidation->isValid()) {
    throw new Exception('Invalid response or certificate');
}
