Library for implement TatraPay gateway (v4.0 with HMAC & ECDSA) from Tatra Banka in Nette framework.

Requirements

Requires PHP 7.1 or later.

Use universal libraty PaySys\PaySys.

Installation

The best way to install Unique is use Composer package PaySys/TatraPay.

$ composer require paysys/tatrapay

Configuration

extensions:
	TatraPay: PaySys\TatraPay\DI\TatraPayExtension

TatraPay:
	mid: '1234'
	key: '64-bit hexadecimal string'

Events

Object PaySys\PaySys\Button

Service PaySys\TatraPay\Security\Response

Example

Generating payment button

Set PaySys\TatraPay\Payment.

Button need PaySys\PaySys\IConfiguration service. Use DI generated factory PaySys\TatraPay\IButtonFactory for getting configured PaySys\PaySys\Button component.

Now set $onPayRequest event on PaySys\PaySys\Button for redirect to TatraPay gateway. Signed redirect URL is genereated by service PaySys\TatraPay\Security\Request->getUrl(PaySys\TatraPay\Payment $payment).

class OrderPresenter extends Presenter
{
	/** @var \PaySys\TatraPay\IButtonFactory @inject */
	public $tatraPayButtonFactory;

	/** @var \PaySys\TatraPay\Security\Request @inject */
	public $tatraPayRequest;

	protected function createComponentTatraPayButton()
	{
		$payment = new \PaySys\TatraPay\Payment("12.34", "00456", "John Doe");
		$button = $this->tatraPayButtonFactory->create($payment);
		$button->onPayRequest[] = function ($payment) {
			$this->redirectUrl($this->TatraPayRequest->getUrl($payment));
		};
		return $button;
	}
}

Process payment response

Event-driven processing

Default is Bank response routed to included presenter TatraPay:TatraPay:process. In this case are automatic called events on service PaySys\TatraPay\Security\Response.

For processing payment by events use for example Kdyby\Events.

Own presenter

Too it's possible write own Nette\Application\UI\Presenter for hnadling payment. In this case are events called same as before example.

class OrderPresenter extends Presenter
{
	/** @var Nette\Http\IRequest @inject */
	public $httpRequest;

	/** @var \PaySys\TatraPay\Security\Response @inject */
	public $bankResponse;

	public function actionProcessTatraPay()
	{
		try {
			$this->bankResponse->paid($this->httpRequest->getQuery());
			// store info about payment
			$this->flashMessage('Thanks for payment.', 'success');
		} catch (\PaySys\PaySys\Exception $e) {
			// log
			$this->flashMessage('Payment failed. Please try it later.', 'danger');
		}
		$this->redirect('finish');
	}
}

Now just add route to configuration:

tatraPay:
	rurl: Order:processTatraPay
