A simple class for interfacing with some of the basic methods of the CyberSource SOAP Toolkit API for processing credit card transactions online.

CyberSource encourages the use of their Simple Order API, which utilizes a custom PHP extension that hasn't been updated since 2007 (and doesn't support 64-bit servers). This class avoids the need to install a custom extension and provides a quick and easy entry point to their SOAP API instead.

The documentation provided by CyberSource is quite lacking. If you need to expand the methods made available your best bet is to look at the Simple Order API documentation and try to emulate it as closely as possible via the SOAP interface. With some trial and error you'll see that it's quite similar.

Include the class in your code and instantiate the CyberSource class with your Merchant ID and Transaction ID:

$c = new CyberSource( $merchant_id, $transaction_id );

A factory pattern is also provided, for easy method chaining:

$result = CyberSource::factory( $merchant_id, $transaction_id )
	->card( '4111111111111111', '12', '2013', '123' )
	->add_item( 5 )
	->charge();

There are several invidivual examples available in the tests directory demonstrating how to call the commonly-used methods.

To run the examples first create a file under tests/config.php with the following keys:

<?php

$merchant_id = 'xxx';
$transaction_id = 'yyy';
$username = 'zzz';
$password = 'vvv';

Then run:

$ /path/to/composer.phar dump-autoload

This will create the autoload file for the classes of the library. You are now ready to execute an example:

php -d error_reporting=-1 -d display_errors tests/auth_amount.php
