# Get Started

In this chapter we are going to setup payum package and do simple purchase using paypal express checkout. Look at sandbox to find more examples.

### Installation

```bash
php composer.phar require payum/payum-laravel-package payum/xxx
```

{% hint style="info" %}
***Note**: Where **payum/xxx** is a payum package, for example it could be **payum/paypal-express-checkout-nvp**. Look at* [*supported gateways*](/payum/supported-gateways.md) *to find out what you can use.*
{% endhint %}

{% hint style="info" %}
***Note**: Use **payum/payum** if you want to install all gateways at once.*
{% endhint %}

Now you have all codes prepared and ready to be used.

### Configuration

Register provider:

```php
<?php
// app/config/app.php

return array(
    'providers' => array(
        'Payum\LaravelPackage\PayumServiceProvider',
    ),
);
```

Configure builder. You are free to use other builder's methods.

In Laravel 4, add the following to bootstrap/start.php or other place where you can use App::resolving method.

```php

App::resolving('payum.builder', function(\Payum\Core\PayumBuilder $payumBuilder) {
    $payumBuilder
        // this method registers filesystem storages, consider to change them to something more
        // sophisticated, like eloquent storage
        ->addDefaultStorages()

        ->addGateway('paypal_ec', [
            'factory' => 'paypal_express_checkout',
            'username' => 'EDIT ME',
            'password' => 'EDIT ME',
            'signature' => 'EDIT ME',
            'sandbox' => true
        ])
    ;
});
```

In Laravel 5, create new service provider or add to the default app/Providers/AppServiceProvider.php register method:

```php
...
public function register()
{
    $this->app->resolving('payum.builder', function(\Payum\Core\PayumBuilder $payumBuilder) {
        $payumBuilder
        // this method registers filesystem storages, consider to change them to something more
        // sophisticated, like eloquent storage
        ->addDefaultStorages()

        ->addGateway('paypal_ec', [
            'factory' => 'paypal_express_checkout',
            'username' => 'EDIT ME',
            'password' => 'EDIT ME',
            'signature' => 'EDIT ME',
            'sandbox' => true
        ]);
    });
}
...
```

### Prepare payment

Lets create a controller where we prepare the payment details.

```php
<?php
// app/controllers/PaypalController.php
namespace App\Http\Controllers; // the path of the controller
use Payum\LaravelPackage\Controller\PayumController;

class PaypalController extends PayumController
{
	public function prepareExpressCheckout()
	{
        $storage = $this->getPayum()->getStorage('Payum\Core\Model\ArrayObject');

        $details = $storage->create();
        $details['PAYMENTREQUEST_0_CURRENCYCODE'] = 'EUR';
        $details['PAYMENTREQUEST_0_AMT'] = 1.23;
        $storage->update($details);

        $captureToken = $this->getPayum()->getTokenFactory()->createCaptureToken('paypal_ec', $details, 'payment_done');

        return \Redirect::to($captureToken->getTargetUrl());
	}
}
```

Here's you may want to modify a `payment_done` route. It is a controller where the payer will be redirected after the payment is done, whenever it is success failed or pending. Read a [dedicated chapter](/payum/laravel/payment-done-controller.md) about how the payment done controller may look like.
