Dwolla off-site gateway support for the Omnipay PHP payment processing library

Omnipay is a framework agnostic, multi-gateway payment processing library for PHP 5.3+. This package implements Dwolla support for Omnipay.

Installation

Omnipay is installed via Composer. omnipay-dwolla is currently not a part of the official Omnipay branch; we are working on this.

And run composer to update your dependencies:

$ curl -s http://getcomposer.org/installer | php
$ php composer.phar update

Basic Usage

The following gateways are provided by this package:

• Dwolla (off-site gateway)

For general usage instructions, please see the main Omnipay repository.

Dwolla API documentation is available here.

In order to get started, first obtain Dwolla API credentials

Initiating a Checkout

Off-site gateway checkouts are initiated by calling the purchase() method.

use Omnipay\Omnipay;

$gateway = Omnipay::create('Dwolla');

$gateway->setKey('An API key!');
$gateway->setSecret('Shh!');
$gateway->setDestinationId('812-111-1234');
$gateway->setReturnUrl('http://your-sweet-app.net/handle_redirect');

// Want sandbox mode?
// $gateway->setSandbox(true);

$response = $gateway->purchase(['amount' => '10.00'])->send();

if ($response->isRedirect()) {
    // Redirect to Dwolla
    $response->redirect();
} else {
    // Something went wrong!
    echo $response->getMessage();
}

Retrieving an already created checkout

If your application would like to retrieve old checkouts, omnipay-dwolla allows you to do so via the capture() method. This somewhat falls ambiguously under OmniPay convention as we also return checkouts which have failed, i.e, which have not been successfully authorized by the user redirected to the off-site gateway.

use Omnipay\Omnipay;

$gateway = Omnipay::create('Dwolla');

$gateway->setKey('An API key!');
$gateway->setSecret('Shh!');

// Want sandbox mode?
// $gateway->setSandbox(true);

$checkout = $gateway->capture(['transactionReference' => 'c271d65c-7b71-421f-a80f-8682bb2ce2c4'])->send();
