$provider = \PayPal::setProvider();
```

    'mode'    => env('PAYPAL_MODE', 'sandbox'), // Can only be 'sandbox' Or 'live'. If empty or invalid, 'live' will be used.
    'sandbox' => [
        'client_id'         => env('PAYPAL_SANDBOX_CLIENT_ID', ''),
        'client_secret'     => env('PAYPAL_SANDBOX_CLIENT_SECRET', ''),
        'app_id'            => 'APP-80W284485P519543T',

        'app_id'            => env('PAYPAL_LIVE_APP_ID', ''),
    ],

    'payment_action' => env('PAYPAL_PAYMENT_ACTION', 'Sale'), // Can only be 'Sale', 'Authorization' or 'Order'
    'currency'       => env('PAYPAL_CURRENCY', 'USD'),
    'notify_url'     => env('PAYPAL_NOTIFY_URL', ''), // Change this accordingly for your application.
    'locale'         => env('PAYPAL_LOCALE', 'en_US'), // force gateway language  i.e. it_IT, es_ES, en_US ... (for express checkout only)
    'validate_ssl'   => env('PAYPAL_VALIDATE_SSL', true), // Validate SSL when creating api client.
];
```

## Override PayPal API Configuration

```php
$config = [
    'mode'    => 'live',
    'live' => [
        'client_id'         => 'PAYPAL_LIVE_CLIENT_ID',
        'client_secret'     => 'PAYPAL_LIVE_CLIENT_SECRET',
        'app_id'            => 'PAYPAL_LIVE_APP_ID',
    ],

    'payment_action' => 'Sale',
    'currency'       => 'USD',
    'notify_url'     => 'https://your-site.com/paypal/notify',
    'locale'         => 'en_US',
    'validate_ssl'   => true,
];
$provider->setApiCredentials($config);
```

## Get Access Token

After setting the PayPal API configuration by calling `setApiCredentials` method. You need to get access token before performing any API calls

```php
$provider->getAccessToken();
```


<a name="usage-currency"></a>
## Set Currency

By default, the currency used is `USD`. If you wish to change it, you may call `setCurrency` method to set a different currency before calling any respective API methods:

$provider->setCurrency('EUR');
```

## Helper Methods

> Please note that in the examples below, the call to `addPlanTrialPricing` is optional and it can be omitted when you are creating subscriptions without trial period.

> `setReturnAndCancelUrl()` is optional. If you set urls you have to use real domains. e.g. localhost, project.test does not work.
