1. Create a new project

Create a new project with the command as below.

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

After the new project has been created, go to your project directory.

cd paypal

2. Install Packages for Paypal Payment Gateway Using Composer

Run the following command.

we will install Laravel-Paypal for laravel 6,7, & 8

composer require srmklive/paypal:~3.0

3. Create PayPal credentials

After installing paypal package, we need client_id and secret_key for paypal integration, so we need to enter in paypal developer mode and create new sandbox account for the same. After login in paypal you need to get the client_id and secret_key as shown below. before getting client_id and secret_key we need to create application. So, check the screenshot below and build an app. Login to the Developer Dashboard.

Click Create Apps.

Fill in the name of the application that was created.

Then you will get the client key and secret key that will be used in the application.

4. Configure the package

After the package installation is complete, you open your project and add the key and secret key that you got in the .env file.

PAYPAL_MODE=sandbox
#Paypal sandbox credential
PAYPAL_SANDBOX_CLIENT_ID=AXELAz06GFLR.............................QNu7zyjuYpFLu1g
PAYPAL_SANDBOX_CLIENT_SECRET=EA9dinW1.............................PUzgVQCz7fK4tqe1-jLZCyHzZ0tDTRAx-6qJdIY933Q

If you want to customize the package’s default configuration options, run the vendor:publish command below.

php artisan vendor:publish --provider "Srmklive\PayPal\Providers\PayPalServiceProvider"

This will create a configuration file config/paypal.php with the details below, which you can modify.

5. Create Routes

Now we need to create an application route that we will test the application test transaction on. Open the route/web.php application route file and add the following new route.

<?phpuse Illuminate\Support\Facades\Route;
use App\Http\Controllers\PayPalController;Route::get('create-transaction', [PayPalController::class, 'createTransaction'])->name('createTransaction');
Route::get('process-transaction', [PayPalController::class, 'processTransaction'])->name('processTransaction');
Route::get('success-transaction', [PayPalController::class, 'successTransaction'])->name('successTransaction');
Route::get('cancel-transaction', [PayPalController::class, 'cancelTransaction'])->name('cancelTransaction');

Create Controller

After we create a route, then next we create a controller using php artisan.

php artisan make:controller PayPalController

We already have a controller in the directory app/Http/Controllers/PayPalController.php. Open it and add the code below.

<?phpnamespace App\Http\Controllers;use Illuminate\Http\Request;
use Srmklive\PayPal\Services\PayPal as PayPalClient;class PayPalController extends Controller
{
    /**
     * create transaction.
     *
     * @return \Illuminate\Http\Response
     */
    public function createTransaction()
    {
        return view('transaction');
    }    /**
     * process transaction.
     *
     * @return \Illuminate\Http\Response
     */
    public function processTransaction(Request $request)
    {
        $provider = new PayPalClient;
        $provider->setApiCredentials(config('paypal'));
        $paypalToken = $provider->getAccessToken();        $response = $provider->createOrder([
            "intent" => "CAPTURE",
            "application_context" => [
                "return_url" => route('successTransaction'),
                "cancel_url" => route('cancelTransaction'),
            ],
            "purchase_units" => [
                0 => [
                    "amount" => [
                        "currency_code" => "USD",
                        "value" => "1000.00"
                    ]
                ]
            ]
        ]);        if (isset($response['id']) && $response['id'] != null) {            // redirect to approve href
            foreach ($response['links'] as $links) {
                if ($links['rel'] == 'approve') {
                    return redirect()->away($links['href']);
                }
            }            return redirect()
                ->route('createTransaction')
                ->with('error', 'Something went wrong.');        } else {
            return redirect()
                ->route('createTransaction')
                ->with('error', $response['message'] ?? 'Something went wrong.');
        }
    }    /**
     * success transaction.
     *
     * @return \Illuminate\Http\Response
     */
    public function successTransaction(Request $request)
    {
        $provider = new PayPalClient;
        $provider->setApiCredentials(config('paypal'));
        $provider->getAccessToken();
        $response = $provider->capturePaymentOrder($request['token']);        if (isset($response['status']) && $response['status'] == 'COMPLETED') {
            return redirect()
                ->route('createTransaction')
                ->with('success', 'Transaction complete.');
        } else {
            return redirect()
                ->route('createTransaction')
                ->with('error', $response['message'] ?? 'Something went wrong.');
        }
    }    /**
     * cancel transaction.
     *
     * @return \Illuminate\Http\Response
     */
    public function cancelTransaction(Request $request)
    {
        return redirect()
            ->route('createTransaction')
            ->with('error', $response['message'] ?? 'You have canceled the transaction.');
    }
}

6. Create blade file to create payment button

We are going to create a view that will direct to process the transaction. Create blade view resources/views/transaction.blade.php file and add below code to it.

7. Run the app

Paypal integration complete. Now we need to make a transaction. Run the Laravel server using the Artisan command below.

php artisan serve

Open it with a url like below. To pay with a PayPal account, you need to create an account create sandbox account.

http://localhost:8000/create-transaction

click Pay, it will display the payment form.

Thus this tutorial I provide, hopefully useful.

Thanks.
