README

This laravel package creates an interface with the PayPal API by generating API requests using the assorted classes available.

I built this package, because at the time, I could not find a suitable package to do what I wanted (though this might be due to poor Google skills.) - so I built this.

The documentation for the API which this package uses can be found here: https://developer.paypal.com/docs/api/payments/v2/

Installation

This is best installed by composer:

composer require drewdan/paypal

Publish the config files using the following command

php artisan vendor:publish --tag=drewdan-paypal-config

Orders

The orders class is the class you would use to create and capture payments from customers.

Creating an Order

use Drewdan\Paypal\Services\Orders\Order;

$order = new Order;

$purchaseUnits = [
	[
		'amount' => [
		    'currency_code' => 'GBP',
		    'value' => 12.50,
	    ],
    ],
];

$applicationContext = [
    'brand_name' => 'My Online Shop',
    'shipping_preference' => 'NO_SHIPPING',
    'user_action' => 'PAY_NOW',
    'return_url' => 'https://localhost/return',
    'cancel_url' => 'https://localhost/cancel',
];

$paypalOrder = $order->create($purchaseUnits, 'CAPTURE', $applicationContext);

return redirect($paypalOrder->getLinkByRel('approve')->href);

The above snippet will create a PayPal Order with a value of £12.50 and return an instance of PaypalOrder. This object contains a helper method to access the PayPal Links returned from the request. You can use this to redirect the user to PayPal to make payment.

The parameter for the application context can be found https://developer.paypal.com/docs/api/orders/v2/#definition-order_application_context

This will authorize the payment, but not capture it. To capture a payment, you will need the Order ID which will be passed in a get request when the user is redirected back. You can use whatever mechanism fits your application to track this Order ID.

Capturing a Payment

use Drewdan\Paypal\Services\Orders\Order;

$order = new Order;
//first retrieve the order from Paypal
$paypalOrder = $order->show(request()->PayerID);

//here you could do any validation you wish to verify the order is correct, checking the order amount etc before capturing the payment

$order->capture($paypalOrder);

Once this is complete, you will have captured the payment.

Captures

Refunding a captured payment

After payment has been completed, you might sometimes need to refund the payment, if for example, you are unable to fulfil the order. The captures class has the ability to show an existing captured payment, or refund it.

The refund method accepts the following parameters:

Parameter	Type	Required	Description
captureId	string	True	This is the capture ID, used to identify the capture to provide the refund against
amount	float	True	This is amount you wish to refund.
currency	string	false	This is the currency in which the refund os given. Defaults to GBP
reason	string	false	You can optionally provide a reason for the refund which will be displayed to the customer
invoiceId	string	false	You can optionally provide an invoice ID if applicable

use Drewdan\Paypal\Services\Payments\Captures;

$client = new Captures;

$capture = $client->refund('captureId', 5.99, 'GBP', 'Some reason', 'Invoice 123');

Showing a captured payment

This call will show the details of a captured payment. They are retrieved via their capture ID. Ideally, when you take and capture a payment you would store the capture ID in a database against a given order, so you can reference it in future to make refunds or view details about the capture.

use Drewdan\Paypal\Services\Payments\Captures;

$client = new Captures;

$capture = $client->show('captureId');
