Integracion Paypal Checkout

  1. Crear una aplicacion en el developer dashboard de paypal en: https://developer.paypal.com/dashboard
  2. Agregaremos las siguientes credenciales al .env de nuestro proyecto
PAYPAL_CLIENT_ID= --Client ID de paypal--
PAYPAL_CLIENT_SECRET= --Secret de paypal--
PAYPAL_CURRENCY=USD

  1. Crear Modelo y Migracion para gestion de datos de los pagos

    Schema::create('paypal_payments', function (Blueprint $table) {
	$table->id();
	$table->string('payment_id');
	$table->string('payer_id');
	$table->string('payer_email');
	$table->float('amount', 10, 2);
	$table->string('currency');
	$table->string('status');
	$table->timestamps();
});

    Y ejecutar migracion para que quede montada la tabla.

  2. Instalar libreria Omnipay para la gestion de pagos e integrar más facil PayPal. Ejecutamos: composer require league/omnipay omnipay/paypal

  3. Crear controlador PaypalPaymentController con comando php artisan make:controller PaypalPaymentController

  4. El controlador debe tener un codigo basico de esta forma:

    private $gateway;

public function __construct()
{
	$this->gateway = Omnipay::create('PayPal_Rest');
	$this->gateway->setClientId(env('PAYPAL_CLIENT_ID'));
	$this->gateway->setSecret(env('PAYPAL_CLIENT_SECRET'));
	$this->gateway->setTestMode(true);
}

public function pay(Request $request)
{
	try {
		$response = $this->gateway->purchase(array(
			'amount' => $request->amount,
			'currency' => env('PAYPAL_CURRENCY'),
			'returnUrl' => url('success'),
			'cancelUrl' => url('error')
		))->send();

		if($response->isRedirect()){
			$response->redirect();
		}else{
			return $response->getMessage();
		}
	} catch (\Throwable $th) {
		return $th->getMessage();
	}
}

  5. En el front deberemos de generar un formulario que envie los datos del pago al endpoint que procesará posteriormente el pago.

    <form action="--endpoint--" method="post">
	@crsf
	<button class="mt-2 btn btn-primary" type="submit">
		Pagar con 
		<i class="fa-2xl fa-brands fa-cc-paypal"></i>
	</button>
</form>

  6. Generar ruta para iniciar el checkout Route::post('paypal', 'PaypalPaymentController@pay')->name('paypal.pay');

  7. Y por ultimo una ruta para procesar el error o el exito de la operacion, asi como recuperar los datos de la transaccion y almacenarlos para controlarlos

Route::post('paypal/success', 'PaypalPaymentController@pay')->name('paypal.success');
Route::post('paypal/error', 'PaypalPaymentController@pay')->name('paypal.error');

Codigo de metodo en el controlador

public function success(Request $request)
    {
        if($request->input('paymentId') && $request->input('PayerID')){
            $transaction = $this->gateway->completePurchase(array(
                'payer_id' => $request->input('PayerID'),
                'transactionReference' => $request->input('paymentId')
            ));

            $response = $transaction->send();

            if($response->isSuccessful()){
                $arr = $response->getData();

                $payment = new PaypalPayment();
                $payment->payment_id = $arr['id'];
                $payment->payer_id = $arr['payer']['payer_info']['payer_id'];
                $payment->payer_email = $arr['payer']['payer_info']['email'];
                $payment->amount = $arr['transactions'][0]['amount']['total'];
                $payment->currency = env('PAYPAL_CURRENCY');
                $payment->status = $arr['state'];

                $payment->save();
            }else{
                return redirect()
                ->route('main')
                ->withErrors('Oops! an error has been detected, try again o contact us.');
            }

            return redirect()
            ->route('main')
            ->withSuccess('Thanks! Your payment has been processed successfully!');
        }else{
            return redirect()
            ->route('main')
            ->withErrors('Oops! an error has been detected, try again o contact us.');
        }
    }

Proximas pruebas o mejoras

  • Probar integracion con asociacion de pagos a traves de la orden como en sitema de pago comun
  • Buscar solucion en formato de modal o in site
  • Crear endpoints para cambios de estados de pagos
