Example payment via Gestpay Payment Page in PHP 5(+)

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

The payment process is explained in Gestpay Docs - Getting Started - see in particular Using Banca Sella Payment Page.

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

How to start the example

1. open the file index.php and change

$shopLogin = 'GESPAYXXXXX';

with your shopLogin.

2. start this webapp on a server with a public IP.
3. Connect to your test merchant back-office and login
4. In Configuration > IP address, insert the public IP of your server
5. 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
6. Pay with one of the cards present in the Notification page.
7. Once you have payed, you'll be redirected by Gestpay on response.php to see the outcome of the transaction.

Debugging

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

1. Declare the SoapClient with the trace option set to true:

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

2. write this line after the request:

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