This is the PHP client for the CyberSource SOAP Toolkit API.

Build Status


The cybersource/sdk-php is available at Packagist. If you want to install SDK from Packagist,add the following dependency to your application's 'composer.json'.

"require": {
  "cybersource/sdk-php": "*"


  • PHP 7.3 or above
  • A CyberSource account. You can create an evaluation account here.
  • A CyberSource transaction key. You will need to set your merchant ID and transaction key in the cybs.ini file in lib/conf. Instructions on obtaining a transaction key can be found here.


You can install the client either via Composer or manually. Before installing, make sure to configure the merchant ID, transaction key, and the appropriate WSDL file URL in cybs.ini. By default, the WSDL file for the client is for API version 1.120 (the latest when this package was updated). Available WSDL file URLs can be browsed at the following locations:

Installing with Composer

You'll first need to make sure you have Composer installed. You can follow the instructions on the official web site. Once Composer is installed, you can enter the project root and run:

Linux: composer.phar install 
Windows: composer install 

If you already have composer installed for the project, you'll need to run the update command as below

Linux: composer.phar update 
Windows: composer update

Then, to use the client, you'll need to include the Composer-generated autoload file:


Manual installation

To use the client manually, include the CyberSource client in your project:


Getting Started

The PHP client will generate the request message headers for you, and will contain the methods specified by the WSDL file.

Creating a simple request

The main method you'll use is runTransaction(). To run a transaction, you'll first need to construct a client to generate a request object, which you can populate with the necessary fields (see documentation for sample requests). The object will be converted into XML, so the properties of the object will need to correspond to the correct XML format.

$client = new CybsSoapClient();
$request = $client->createRequest();

$card = new stdClass();
$card->accountNumber = '4111111111111111';
$card->expirationMonth = '12';
$card->expirationYear = '2020';
$request->card = $card;

// Populate $request here with other necessary properties

$reply = $client->runTransaction($request);

Creating a request from XML

You can create a request from XML either in a file or from an XML string. The XML request format is described in the Using XML section here. Here's how to run a transaction from an XML file:

$referenceCode = 'your_merchant_reference_code';
$client = new CybsSoapClient();
$reply = $client->runTransactionFromFile('path/to/my.xml', $referenceCode);

Or, you can create your own XML string and use that instead:

$xml = "";
// Populate $xml
$client = new CybsSoapClient();

Using name-value pairs

In order to run transactions using name-value pairs, make sure to set the value for the WSDL for the NVP transaction processor in cybs.ini. Then use the CybsNameValuePairClient as so:

$client = new CybsNameValuePairClient();
$request = array();
$request['ccAuthService_run'] = 'true';
$request['merchantID'] = 'my_merchant_id';
$request['merchantReferenceCode'] = $'my_reference_code';
// Populate $request
$reply = $client->runTransaction($request);

Running the Samples

After configuring your merchant ID and transaction key in cybs.ini, the samples in the samples directory can be run from the project root. For example:

php samples/Sale.php

The samples will output the response object for each request if successful. Note that the samples contain test data and should not be run in a live environment.

Meta Key support

Meta Key is a key generated by an entity that can be used to authenticate on behalf of other entities provided that the entity which holds key is a parent entity or associated as a partner.

SOAP PHP SDK supports meta key by default. Additional detail regarding cybs.ini changes.

merchantID=<Refers to portfolio or account MID>
transaction_key=<Soap password generated for meta key>
Send transacting merchantID in the sample request.


In order to run tests, you'll need PHPUnit. You'll also need to use Composer for autoloading. If you used Composer to install the client, this should already be set up. Otherwise, to use Composer for autoloading only, from the project root run

composer.phar dump-autoload

If you installed PHPUnit with Composer, run the tests from the project root with the command vendor/bin/phpunit.
