Getting Started




v2.0.0 - 2013-11-17

Package Separation

As of 2.0, Omnipay has been split into separate packages. Core functionality is contained within the omnipay/common repository, and all gateways have their own repositories. This means that if your project only requires on a single gateway, you can load it without installing all of the other gateways. All officially supported gateways can be found under the Omnipay GitHub organization.

If you want to install all gateways, you can still use the omnipay/omnipay metapackage in composer.json:

    "require": {
        "omnipay/omnipay": "~2.0"

Alternatively, if you want to migrate to an individual gateway, simply change your composer.json file to reference the specific gateway (omnipay/common will be included for you automatically):

    "require": {
        "omnipay/paypal": "~2.0"

Breaking Changes

The GatewayFactory class can no longer be called in a static fashion. To help those who want to use dependency injection, you can now create an instance of GatewayFactory:

$factory = new GatewayFactory();
$gateway = $factory->create('PayPal_Express');

The following code is invalid and will no longer work:

$gateway = GatewayFactory::create('PayPal_Express'); // will cause PHP error!

If you want to continue to use static methods for simplicity, you can use the new Omnipay class:

// at the top of your PHP file
use Omnipay\Omnipay;

// further down when you need to create the gateway
$gateway = Omnipay::create('PayPal_Express');

Behind the scenes, this will create a GatewayFactory instance for you and call the appropriate method on it.


Omnipay now supports sending line-item data to gateways. Currently this is only supported by the PayPal gateway. Line item details can be added to a request like so:

    array('name' => 'Food', 'quantity' => 1, 'price' => '40.00'),
    array('name' => 'Drinks', 'quantity' => 2, 'price' => '6.00'),

For more details, see the pull request.

Omnipay now also supports modifying request data before it is sent to the gateway.. This allows you to send arbitrary custom data with a request, even if Omnipay doesn’t support a parameter directly. To modify the request data, instead of calling send() directly on the request, you may use the new sendData() method:

// standard method - send default data
$response = $request->send();

// new method - get and send custom data
$data = $request->getData();
$data['customParameter'] = true;

$response = $request->sendData($data);
