Introduction

Laravel plugin For Processing Payments Through Paypal. Using this plugin you can process or refund payments and handle IPN (Instant Payment Notification) from PayPal in your Laravel application.

Currently only PayPal Express Checkout, Adaptive Payments API & In-Context Checkout Is Supported.

Installation

Use following command to install:

composer require saleemepoch/paypal

Add the service provider to your $providers array in config/app.php file like:

'saleemepoch\PayPal\Providers\PayPalServiceProvider' // Laravel 5

saleemepoch\PayPal\Providers\PayPalServiceProvider::class // Laravel 5.1 or greater

Add the alias to your $aliases array in config/app.php file like:

'PayPal' => 'saleemepoch\PayPal\Facades\PayPal' // Laravel 5

'PayPal' => saleemepoch\PayPal\Facades\PayPal::class // Laravel 5.1 or greater

Run the following command to publish configuration:

php artisan vendor:publish

Configuration

After installation, you will need to add your paypal settings. Following is the code you will find in config/paypal.php, which you should update accordingly.

return [
    'mode' => 'sandbox', // Can only be 'sandbox' Or 'live'. If empty or invalid, 'live' will be used.
    'sandbox' => [
        'username' => '',
        'password' => '',
        'secret' => '',
        'certificate' => '',
        /*
        If using In-Context Checkout uncomment the following line. Otherwise,
        leave it commented and it will use the default gateway: https://www.sandbox.paypal.com
        */
        //'gateway_url' => 'https://www.sandbox.paypal.com/checkoutnow/',
    ],
    'live' => [
        'username' => '',
        'password' => '',
        'secret' => '',
        'certificate' => '',
		/*
		If using In-Context Checkout uncomment the following line. Otherwise,
		leave it commented and it will use the default gateway: https://www.sandbox.paypal.com
		*/
		//'gateway_url' => 'https://www.paypal.com/checkoutnow/',
    ],
    'payment_action' => 'Sale', // Can Only Be 'Sale', 'Authorization', 'Order'
    'currency' => 'USD',
    'notify_url' => '', // Change this accordingly for your application.
];

In-Context Checkout

Apart from changing the gateway (as mentioned above), remember to also include required JS without which In-Context wouldn't work.

Usage

Set Providers

PayPal::setProvider('express_checkout');    // To use PayPal Express Checkout API (Used by default)
PayPal::setProvider('adaptive_payments');   // To use PayPal Adaptive Payments API

Express Checkout

$data = [];
$data['items'] = [
    [
        'name' => 'Product 1',
        'price' => 9.99
    ],
    [
        'name' => 'Product 2',
        'price' => 4.99
    ]
];

$data['invoice_id'] = 1;
$data['invoice_description'] = "Order #$data[invoice_id] Invoice";
$data['return_url'] = url('/payment/success');
$data['cancel_url'] = url('/cart');

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

$data['total'] = $total;

SetExpressCheckout

$response = PayPal::getProvider()->setExpressCheckout($data);

// Use the following line when creating recurring payment profiles (subscriptions)
$response = PayPal::getProvider()->setExpressCheckout($data, true);

 // This will redirect user to PayPal
return redirect($response['paypal_link']);

GetExpressCheckoutDetails

$response = PayPal::getProvider()->getExpressCheckoutDetails($token);

DoExpressCheckoutPayment

// Note that 'token', 'PayerID' are values returned by PayPal when it redirects to success page after successful verification of user's PayPal info.
$response = PayPal::getProvider()->doExpressCheckoutPayment($data, $token, $PayerID);

RefundTransaction

$response = PayPal::getProvider()->refundTransaction($transactionid);

CreateBillingAgreement

// The $token is the value returned from SetExpressCheckout API call
$response = PayPal::getProvider()->createBillingAgreement($token);

CreateRecurringPaymentsProfile

// The $token is the value returned from SetExpressCheckout API call
$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'
    'BILLINGFREQUENCY' => 12, // set 12 for monthly, 52 for yearly
    'AMT' => 10, // Billing amount for each billing cycle
    'CURRENCYCODE' => 'USD', // Currency code 
    'TRIALBILLINGPERIOD' => 'Day',  // (Optional) Can be 'Day', 'Week', 'SemiMonth', 'Month', 'Year'
    'TRIALBILLINGFREQUENCY' => 10, // (Optional) set 12 for monthly, 52 for yearly 
    'TRIALTOTALBILLINGCYCLES' => 1, // (Optional) Change it accordingly
    'TRIALAMT' => 0, // (Optional) Change it accordingly
];
$response = PayPal::getProvider()->createRecurringPaymentsProfile($data, $token);

GetRecurringPaymentsProfileDetails

$response = PayPal::getProvider()->getRecurringPaymentsProfileDetails($profileid);

UpdateRecurringPaymentsProfile

$response = PayPal::getProvider()->updateRecurringPaymentsProfile($data, $profileid);

ManageRecurringPaymentsProfileStatus

// Cancel recurring payment profile
$response = PayPal::getProvider()->cancelRecurringPaymentsProfile($profileid);

// Suspend recurring payment profile
$response = PayPal::getProvider()->suspendRecurringPaymentsProfile($profileid);

// Reactivate recurring payment profile
$response = PayPal::getProvider()->reactivateRecurringPaymentsProfile($profileid);

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:

First add the ipn/notify tp your routes file:

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.
```
'ipn/notify'
```

Then in the controller where you are handling IPN, do the following:

// Put this above controller definition
use saleemepoch\PayPal\Traits\IPNResponse As PayPalIPN;

// Then add the following before function declaration
use PayPalIPN;

The above step saves the PayPal IPN response as ipn in session. Following is the code you can change to your own requirements for handling IPN:

/**
 * Retrieve IPN Response From PayPal
 *
 * @param \Illuminate\Http\Request $request
 */
public function postNotify(Request $request)
{
    $post = [];
    $request_params = $request->all();

    foreach ($request_params as $key=>$value)
        $post[$key] = $value;

    $post['cmd'] = '_notify-validate';

    $response = $this->verifyIPN($post);

    session([
        'ipn' => $response
    ]);
}
