This repository is an example project to show how to implement a payment via Gestpay payment page.

This repo uses the native SOAP extensions, present in PHP5+. If you are in a lower version of php, check php4 repository.

File	Description
`index.php`	is the main entry point for the application. tweaking this page you will be able to change the amount, or the currency, and so on.
`response.php`	when the payment is completed, Gestpay will redirect to this file to show to the user the payment status. `response.php` will decrypt the encrypted string and then it will show the SOAP message received - in the form of an array.
`phpinfo.php`	A simple page to check your php version and your server software.
`functions.php`	a file containing utility functions

open the file index.php and change
```
$shopLogin = 'GESPAYXXXXX';
```
with your shopLogin.
start this webapp on a server with a public IP.
Connect to your test merchant back-office and login
In Configuration > IP address, insert the public IP of your server
In the same page click on Response Address and insert:
- URL for positive response: <<your_server_address>>/response.php
- URL for negative response: <<your_server_address>>/response.php
- URL Server to Server: <<your_server_address>>/response.php
Pay with one of the cards present in the Notification page.
Once you have payed, you’ll be redirected by Gestpay on response.php to see the outcome of the transaction.

If you want to see the request you send to Gestpay:

Declare the SoapClient with the trace option set to true:

$client = new SoapClient($wsdl, array('trace' => 1));

write this line after the request:

echo "REQUEST:\n<pre>" . htmlentities($client->__getLastRequest()) . "</pre>\n";
