How To Integrate Paypal Payment Gateway In Laravel 10

As a Laravel 10 developer, I understand the importance of providing a secure and user-friendly payment experience for online businesses. That's why integrating a reliable payment gateway like PayPal into your Laravel 10 application can be a game-changer. If you're looking to integrate PayPal into your Laravel 10 project, you're in the right place.

In this comprehensive guide, I will walk you through the step-by-step process of integrating the PayPal payment gateway into your Laravel 10 application. Together, we'll cover all the necessary steps, from setting up a PayPal Business account to implementing the payment functionality within your Laravel codebase.

By the end of this tutorial, you'll have a solid understanding of how to harness the power of Laravel's features and seamlessly integrate PayPal's API for secure and efficient payment processing in your application.

PayPal is an American company operating a worldwide online payments system that supports online money transfers and serves as an electronic alternative to traditional paper methods like checks and money orders.

So, let's dive right in and discover the incredible potential of PayPal integration in Laravel 10.

Ensure you have a Laravel 10 project set up and ready for integration. If you haven't created a Laravel project yet, you can use the following command to create one.

composer create-project --prefer-dist laravel/laravel paypal_payment_integration

 

To integrate PayPal payment gateway in Laravel 10, you'll need to configure your database settings. Follow these steps.

Open the .env file located in the root directory of your Laravel project.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel
DB_USERNAME=root
DB_PASSWORD=

 

Open the terminal, navigate to your Laravel project directory, and run the following command to install the PayPal SDK package.

composer require paypal/rest-api-sdk-php

After installing the PayPal package for integration, the next step is to obtain the client_id and secret_key required for PayPal integration. To obtain these credentials, you will need to log in to the PayPal developer mode and create a new sandbox account. Here's a step-by-step guide:

1. Visit the PayPal developer website (https://developer.paypal.com/) and log in to your PayPal account.

2. Once logged in, navigate to the developer dashboard.

3. In the dashboard, click on "My Apps & Credentials" or a similar option, depending on the layout of the developer dashboard.

4. Next, click on the "Create App" button to create a new application for your PayPal integration.

5. Provide a suitable name for your application and select the sandbox environment.

6. After creating the application, you will be redirected to the application details page. Here, you will find the client_id and secret_key under the "Credentials" section.

7. Take note of the client_id and secret_key values, as you will need them to configure the PayPal integration in your Laravel application.

 

 

To configure the PayPal integration in Laravel 10, you will need to create a paypal.php configuration file. This file will contain the necessary settings for your PayPal integration. Follow these steps to create and configure the paypal.php file:

1. Open your Laravel project in your preferred code editor.

2. Navigate to the config directory located in the root of your project.

3. Inside the config directory, create a new file named paypal.php.

4. Open the paypal.php file and add the following code:

<?php 
return [ 
    'client_id' => 'XXXXXX',
	'secret' => 'XXXXXX',
    'settings' => array(
        'mode' => 'sandbox',
        'http.ConnectionTimeOut' => 1000,
        'log.LogEnabled' => true,
        'log.FileName' => storage_path() . '/logs/paypal.log',
        'log.LogLevel' => 'FINE'
    ),
];

 

Create a route and corresponding controller method for initiating the PayPal payment. In your routes/web.php file, add the following route.

<?php

use Illuminate\Support\Facades\Route;

Route::get('paywithpaypal', array('as' => 'paywithpaypal','uses' => 'PaypalController@payWithPaypal',));
Route::post('paypal', array('as' => 'paypal','uses' => 'PaypalController@postPaymentWithpaypal',));
Route::get('paypal', array('as' => 'status','uses' => 'PaypalController@getPaymentStatus',));

 

Then, create a new controller using the command.

php artisan make:controller PaypalController

In the PaypalController, add the payWithPayPal and postPaymentWithpaypal method.

<?php

namespace App\Http\Controllers;

use App\Http\Requests;
use Illuminate\Http\Request;
use Validator;
use URL;
use Session;
use Redirect;
use Input;
use PayPal\Rest\ApiContext;
use PayPal\Auth\OAuthTokenCredential;
use PayPal\Api\Amount;
use PayPal\Api\Details;
use PayPal\Api\Item;
use PayPal\Api\ItemList;
use PayPal\Api\Payer;
use PayPal\Api\Payment;
use PayPal\Api\RedirectUrls;
use PayPal\Api\ExecutePayment;
use PayPal\Api\PaymentExecution;
use PayPal\Api\Transaction;

class PaypalController extends Controller
{
    private $_api_context;
    
    public function __construct()
    {
            
        $paypal_configuration = \Config::get('paypal');
        $this->_api_context = new ApiContext(new OAuthTokenCredential($paypal_configuration['client_id'], $paypal_configuration['secret']));
        $this->_api_context->setConfig($paypal_configuration['settings']);
    }

    public function payWithPaypal()
    {
        return view('paywithpaypal');
    }

    public function postPaymentWithpaypal(Request $request)
    {
        $payer = new Payer();
        $payer->setPaymentMethod('paypal');

    	$item_1 = new Item();

        $item_1->setName('Product 1')
            ->setCurrency('USD')
            ->setQuantity(1)
            ->setPrice($request->get('amount'));

        $item_list = new ItemList();
        $item_list->setItems(array($item_1));

        $amount = new Amount();
        $amount->setCurrency('USD')
            ->setTotal($request->get('amount'));

        $transaction = new Transaction();
        $transaction->setAmount($amount)
            ->setItemList($item_list)
            ->setDescription('Enter Your transaction description');

        $redirect_urls = new RedirectUrls();
        $redirect_urls->setReturnUrl(URL::route('status'))
            ->setCancelUrl(URL::route('status'));

        $payment = new Payment();
        $payment->setIntent('Sale')
            ->setPayer($payer)
            ->setRedirectUrls($redirect_urls)
            ->setTransactions(array($transaction));            
        try {
            $payment->create($this->_api_context);
        } catch (\PayPal\Exception\PPConnectionException $ex) {
            if (\Config::get('app.debug')) {
                \Session::put('error','Connection timeout');
                return Redirect::route('paywithpaypal');                
            } else {
                \Session::put('error','Some error occur, sorry for inconvenient');
                return Redirect::route('paywithpaypal');                
            }
        }

        foreach($payment->getLinks() as $link) {
            if($link->getRel() == 'approval_url') {
                $redirect_url = $link->getHref();
                break;
            }
        }
        
        Session::put('paypal_payment_id', $payment->getId());

        if(isset($redirect_url)) {            
            return Redirect::away($redirect_url);
        }

        \Session::put('error','Unknown error occurred');
    	return Redirect::route('paywithpaypal');
    }

    public function getPaymentStatus(Request $request)
    {        
        $payment_id = Session::get('paypal_payment_id');

        Session::forget('paypal_payment_id');
        if (empty($request->input('PayerID')) || empty($request->input('token'))) {
            \Session::put('error','Payment failed');
            return Redirect::route('paywithpaypal');
        }
        $payment = Payment::get($payment_id, $this->_api_context);        
        $execution = new PaymentExecution();
        $execution->setPayerId($request->input('PayerID'));        
        $result = $payment->execute($execution, $this->_api_context);
        
        if ($result->getState() == 'approved') {         
            \Session::put('success','Payment success !!');
            return Redirect::route('paywithpaypal');
        }

        \Session::put('error','Payment failed !!');
		return Redirect::route('paywithpaypal');
    }
}
