How to Integrate Paypal In Laravel?

6 minutes read

Integrating PayPal in Laravel involves several steps. First, you need to create a PayPal developer account and get your API credentials. Next, you need to install the PayPal SDK using Composer. Once installed, you can use the PayPal APIs to handle payments and transactions in your Laravel application. You will need to create routes, controllers, and views to handle the PayPal payment process. Additionally, you can use event listeners and middleware to handle the PayPal payment responses and updates. Finally, test the PayPal integration in a sandbox environment before deploying it to production. Overall, integrating PayPal in Laravel requires proper configuration and implementation of the PayPal SDK and APIs to handle payments securely and efficiently.

        $apiPassword = $paypalConfig['api_password'];
        $apiSignature = $paypalConfig['api_signature'];

        $service = new AdaptivePaymentsService([
            'apiUsername' => $apiUserName,
            'apiPassword' => $apiPassword,
            'apiSignature' => $apiSignature,
            'sandbox' => $paypalConfig['sandbox']
        ]);

        // Make API calls to create and process payments
    }
}


  1. Set up routes to access the PayPal Adaptive Payments functionality in your Laravel application. Define routes in the routes/web.php file:
1
Route::get('/create-payment', [PayPalController::class, 'createPayment']);


  1. Use the PayPal Adaptive Payments SDK methods to create, execute, and process payments based on your application's requirements.
  2. Test the integration by making a payment using the Adaptive Payments SDK functions.


By following these steps, you can integrate PayPal Adaptive Payments in your Laravel application. Make sure to handle errors and exceptions properly and implement a secure payment flow to ensure a smooth transaction process for your users.

            new OAuthTokenCredential(config('services.paypal.client_id'), config('services.paypal.secret'))
        );

        $apiContext->setConfig(['mode' => config('services.paypal.mode')]);

        $payer = new Payer();
        $payer->setPaymentMethod("paypal");

        $item = new Item();
        $item->setName('Product Name')
            ->setCurrency('USD')
            ->setQuantity(1)
            ->setPrice(10);

        $itemList = new ItemList();
        $itemList->setItems([$item]);

        $amount = new Amount();
        $amount->setCurrency("USD")
             ->setTotal(10);

        $transaction = new Transaction();
        $transaction->setAmount($amount)

        } catch (Exception $ex) {
            dd($ex);
        }
