[Omnipay](https://github.com/thephpleague/omnipay) is a framework agnostic, multi-gateway payment
processing library for PHP. This package implements PayPal support for Omnipay.

## Installation

Omnipay is installed via [Composer](http://getcomposer.org/). To install, simply require `league/omnipay` and `omnipay/paypal` with Composer:

```
composer require league/omnipay omnipay/paypal
```


## Basic Usage

The following gateways are provided by this package:

* PayPal_Express (PayPal Express Checkout)
* PayPal_ExpressInContext (PayPal Express In-Context Checkout)
* PayPal_Pro (PayPal Website Payments Pro)
* PayPal_Rest (Paypal Rest API)

For general usage instructions, please see the main [Omnipay](https://github.com/thephpleague/omnipay)
repository.

## Quirks

The transaction reference obtained from the purchase() response can't be used to refund a purchase. The transaction reference from the completePurchase() response is the one that should be used.

## Out Of Scope

Omnipay does not cover recurring payments or billing agreements, and so those features are not included in this package. Extensions to this gateway are always welcome.
