Evo drivers for the Omnipay PHP payment processing library

This driver supports the following services:

• Three Step Redirect API. Sends transaction information, receives a URL. Show card form, posting to that URL. On return, extract the payment information via a token.
• Remote Evo Payment Gateway (DPG) service. This service seems to be deprecated now. Payment information is sent and received via XML messages. Customers typically stay on the originating website with this method of integration.

Installation

The Evo Omnipay driver is installed via Composer. To install, simply add it to your composer.json file:

{
    "require": {
        "digitickets/omnipay-evo": "~2.0"
    }
}

And run composer to update your dependencies:

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

Basic Usage

The three step redirect API driver supports two transaction types:

• Purchase (the way the service initiates a transaction is not supported by Omnipay, so there is a non-standard "formUrl" method instead of the usual "purchase" method. "complete purchase" follows the standards)
• Refund (done in a standard way)

The DPG driver (possibly deprecated now) supports two transaction types:

• Purchase (including 3D Secure support if card holder is registered)
• Refund (you will need to send Evo's reference from the original transaction as the 'transactionReference' parameter.)

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