, _(*13)

Usage

Following are some ways through which you can access the paypal provider:, _(*14)

// Import the class namespaces first, before using it directly
use Srmklive\PayPal\Services\ExpressCheckout;
use Srmklive\PayPal\Services\AdaptivePayments;

$provider = new ExpressCheckout;      // To use express checkout.
$provider = new AdaptivePayments;     // To use adaptive payments.

// Through facade. No need to import namespaces
$provider = PayPal::setProvider('express_checkout');      // To use express checkout(used by default).
$provider = PayPal::setProvider('adaptive_payments');     // To use adaptive payments.

, _(*15)

Override PayPal API Configuration

You can override PayPal API configuration by calling setApiCredentials method:, _(*16)

$provider->setApiCredentials($config);

, _(*17)

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:, _(*18)

$provider->setCurrency('EUR')->setExpressCheckout($data);

, _(*19)

Additional PayPal API Parameters

By default only a specific set of parameters are used for PayPal API calls. However, if you wish specify any other additional parameters you may call the addOptions method before calling any respective API methods:, _(*20)

$options = [
    'BRANDNAME' => 'MyBrand',
    'LOGOIMG' => 'https://example.com/mylogo.png',
    'CHANNELTYPE' => 'Merchant'
];

$provider->addOptions($options)->setExpressCheckout($data);

Warning: Any parameters should be referenced accordingly to the API call you will perform. For example, if you are performing SetExpressCheckout, then you must provide the parameters as documented by PayPal for SetExpressCheckout to addOptions method., _(*21)

$data = [];
$data['items'] = [

```

$startdate = Carbon::now()->toAtomString();
$profile_desc = !empty($data['subscription_desc']) ?
            $data['subscription_desc'] : $data['invoice_description'];
$data = [
    'PROFILESTARTDATE' => $startdate,
    'DESC' => $profile_desc,
    'BILLINGPERIOD' => 'Month', // Can be 'Day', 'Week', 'SemiMonth', 'Month', 'Year'

// Reactivate recurring payment profile
$response = $provider->reactivateRecurringPaymentsProfile($profileid);    
```

, _(*34)

Adaptive Payments

To use adaptive payments, you must set the provider to use Adaptive Payments:, _(*35)

PayPal::setProvider('adaptive_payments');

* Pay, _(*36)


// Change the values accordingly for your application
$data = [
    'receivers'  => [
        [
            'email' => 'johndoe@example.com',
            'amount' => 10,
            'primary' => true,
        ],
        [
            'email' => 'janedoe@example.com',
            'amount' => 5,
            'primary' => false
        ]
    ],
    'payer' => 'EACHRECEIVER', // (Optional) Describes who pays PayPal fees. Allowed values are: 'SENDER', 'PRIMARYRECEIVER', 'EACHRECEIVER' (Default), 'SECONDARYONLY'
    'return_url' => url('payment/success'), 
    'cancel_url' => url('payment/cancel'),
];

$response = $provider->createPayRequest($data);

// The above API call will return the following values if successful:
// 'responseEnvelope.ack', 'payKey', 'paymentExecStatus'

Next, you need to redirect the user to PayPal to authorize the payment, _(*37)

$redirect_url = $provider->getRedirectUrl('approved', $response['payKey']);

return redirect($redirect_url);

, _(*38)

Handling PayPal IPN

You can also handle Instant Payment Notifications from PayPal. Suppose you have set IPN URL to http://example.com/ipn/notify/ in PayPal. To handle IPN you should do the following:, _(*39)

First add the ipn/notify tp your routes file:, _(*40)

Route::post('ipn/notify','PayPalController@postNotify'); // Change it accordingly in your application

Open App\Http\Middleware\VerifyCsrfToken.php and add your IPN route to $excluded routes variable., _(*41)
```
'ipn/notify'
```

Write the following code in the function where you will parse IPN response:, _(*42)

/**
 * Retrieve IPN Response From PayPal
 *
 * @param \Illuminate\Http\Request $request
 */
public function postNotify(Request $request)
{
    // Import the namespace Srmklive\PayPal\Services\ExpressCheckout first in your controller.
    $provider = new ExpressCheckout;

    $request->merge(['cmd' => '_notify-validate']);
    $post = $request->all();        

    $response = (string) $provider->verifyIPN($post);

    if ($response === 'VERIFIED') {                      
        // Your code goes here ...
    }                            
}

, _(*43)

Create Subscriptions

For example, you want to create a recurring subscriptions on paypal, first pass data to SetExpressCheckout API call in following format:

// Always update the code below accordingly to your own requirements.
$data = [];

$data['items'] = [
    [
        'name'  => "Monthly Subscription",
        'price' => 0,
        'qty'   => 1,
    ],
];

$data['subscription_desc'] = "Monthly Subscription #1";
$data['invoice_id'] = 1;
$data['invoice_description'] = "Monthly Subscription #1";
$data['return_url'] = url('/paypal/ec-checkout-success?mode=recurring');
$data['cancel_url'] = url('/');

$total = 0;
foreach ($data['items'] as $item) {
    $total += $item['price'] * $item['qty'];
}

$data['total'] = $total;

//give a discount of 10% of the order amount
$data['shipping_discount'] = round((10 / 100) * $total, 2);

Next perform the remaining steps listed in SetExpressCheckout.
Next perform the exact steps listed in GetExpressCheckoutDetails.
Finally do the following for CreateRecurringPaymentsProfile

$amount = 9.99;
$description = "Monthly Subscription #1";
$response = $provider->createMonthlySubscription($token, $amount, $description);

// To create recurring yearly subscription on PayPal
$response = $provider->createYearlySubscription($token, $amount, $description);
