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

Installation

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

{
    "require": {
        "clippings/omnipay-paypal": "~0.1"
    }
}

And run composer to update your dependencies:

$ php composer.phar update

Basic Usage

The following gateways are provided by this package:

PaypalRest

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

In order to use this gateway, you need to provide apiKey and clientId.

$gateway = Omnipay::create('PaypalRest');
$gateway->setClientId('abc123');
$gateway->setSecret('abc123');

For a successful purchase you need to provide amount,currency:

$purchase = $gateway->purchase(array(
    'currency' => 'GBP',
    'amount' => '15.00',
    'description' => 'This is a purchase',
));

Funding methods

You can use 3 different methods for paying for purchases

Paypal Redirect

If you do not provide any payment methods, purchase() method will generate a redirect response.

$purchase = $gateway->purchase(array(
    'currency' => 'GBP',
    'amount' => '15.00',
    'description' => 'This is a purchase',
    'redirectUrl' => 'http://example.com/completed',
    'cancelUrl' => 'http://example.com/cancel',
));

$response = $purchase->send();

// redirect to $response->getRedirectUrl()
$response->redirect();
$key = $response->getTransactionReference();

// You'll need to pass $key as well as "payerid" query parameter that you'll get from paypal redirecting back to your site

$completePurchase = $gateway->completePurchase(array(
    'transactionReference' => $key,
    'payerId' => $_GET['PAYERID'],
));

$response2 = $completePurchase->send();

Credit card reference

You can store user's credit cards within paypal's vault, and use a reference to that for purchases.

$createCard = $gateway->createCard(array(
    'card' => ...,
    'payerId' => 'payer id',
));

$response = $createCard->send();
$cardId = $response->getTransactionReference();

$purchase = $gateway->purchase(array(
    'currency' => 'GBP',
    'amount' => '15.00',
    'cardReference' => $cardId,
));

$response = $purchase->send();

Directly with a credit card

$purchase = $gateway->purchase(array(
    'currency' => 'GBP',
    'amount' => '15.00',
    'card' => ...,
));

$response = $purchase->send();

Authorization

Authorisation, capture and void are supported too. It works the same way as purchase, but you'll need to "capture" or "void" afterwords

$authorise = $gateway->authorise(array(
    'currency' => 'GBP',
    'amount' => '15.00',
    'card' => ...,
));

$response = $authorise->send();
$id = $response->getTransactionReference();

$capture = $gateway->capture(array(
    'transactionReference' => $id,
    'amount' => '15.00',
));

$capture->send();

// Or

$capture = $gateway->void(array(
    'transactionReference' => $id,
));

$capture->send();

Refund

$refund = $gateway->refund(array(
    'transactionReference' => $id,
));

$refund->send();

// If you are refunding a capture
$refund = $gateway->refund(array(
    'transactionReference' => $id,
    'type' => 'capture'
));

$refund->send();

// Partial refund
$refund = $gateway->refund(array(
    'transactionReference' => $id,
    'amount' => '10.00'
    'currency' => 'GBP'
));

$refund->send();

Credit Card Vault

createCard, updateCard and deleteCard are supported too.

$createCard = $gateway->createCard(array(
    'card' => ...,
    'payerId' => '123123' // Optional, if set, will be required when referencing for a purchase later
));

$response = $createCard->send();
$cardReference = $response->getTransactionReference();

$updateCard = $gateway->updateCard(array(
    'card' => ...,
));

$deleteCard = $gateway->deleteCard(array(
    'card' => ...,
));
