Route::get('paypal', array('as' => 'status','uses' => '[email protected]',));

Step : 6 Create PaypalController

[ADDCODE]

Now create PaypalController.php file in app/Http/Controllers folder like this way.

<?php
namespace AppHttpControllers;

use AppHttpRequests;
use IlluminateHttpRequest;
use Validator;
use URL;
use Session;
use Redirect;
use Input;

/** All Paypal Details class **/
use PayPalRestApiContext;
use PayPalAuthOAuthTokenCredential;
use PayPalApiAmount;
use PayPalApiDetails;
use PayPalApiItem;
use PayPalApiItemList;
use PayPalApiPayer;
use PayPalApiPayment;
use PayPalApiRedirectUrls;
use PayPalApiExecutePayment;
use PayPalApiPaymentExecution;
use PayPalApiTransaction;

class AddMoneyController extends HomeController
{
    private $_api_context;
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
        
        /** setup PayPal api context **/
        $paypal_conf = Config::get('paypal');
        $this->_api_context = new ApiContext(new OAuthTokenCredential($paypal_conf['client_id'], $paypal_conf['secret']));
        $this->_api_context->setConfig($paypal_conf['settings']);
    }

    /**
     * Show the application paywith paypalpage.
     *
     * @return IlluminateHttpResponse
     */
    public function payWithPaypal()
    {
        return view('paywithpaypal');
    }

    /**
     * Store a details of payment with paypal.
     *
     * @param  IlluminateHttpRequest  $request
     * @return IlluminateHttpResponse
     */
    public function postPaymentWithpaypal(Request $request)
    {
        $payer = new Payer();
        $payer->setPaymentMethod('paypal');

    	$item_1 = new Item();

        $item_1->setName('Item 1') /** item name **/
            ->setCurrency('USD')
            ->setQuantity(1)
            ->setPrice($request->get('amount')); /** unit price **/

        $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('Your transaction description');

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

        $payment = new Payment();
        $payment->setIntent('Sale')
            ->setPayer($payer)
            ->setRedirectUrls($redirect_urls)
            ->setTransactions(array($transaction));
            /** dd($payment->create($this->_api_context));exit; **/
        try {
            $payment->create($this->_api_context);
        } catch (PayPalExceptionPPConnectionException $ex) {
            if (Config::get('app.debug')) {
                Session::put('error','Connection timeout');
                return Redirect::route('paywithpaypal');
                /** echo "Exception: " . $ex->getMessage() . PHP_EOL; **/
                /** $err_data = json_decode($ex->getData(), true); **/
                /** exit; **/
            } else {
                Session::put('error','Some error occur, sorry for inconvenient');
                return Redirect::route('paywithpaypal');
                /** die('Some error occur, sorry for inconvenient'); **/
            }
        }

        foreach($payment->getLinks() as $link) {
            if($link->getRel() == 'approval_url') {
                $redirect_url = $link->getHref();
                break;
            }
        }

        /** add payment ID to session **/
        Session::put('paypal_payment_id', $payment->getId());

        if(isset($redirect_url)) {
            /** redirect to paypal **/
            return Redirect::away($redirect_url);
        }

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

    public function getPaymentStatus()
    {
        /** Get the payment ID before session clear **/
        $payment_id = Session::get('paypal_payment_id');
        /** clear the session payment ID **/
        Session::forget('paypal_payment_id');
        if (empty(Input::get('PayerID')) || empty(Input::get('token'))) {
            Session::put('error','Payment failed');
            return Redirect::route('paywithpaypal');
        }
        $payment = Payment::get($payment_id, $this->_api_context);
        /** PaymentExecution object includes information necessary **/
        /** to execute a PayPal account payment. **/
        /** The payer_id is added to the request query parameters **/
        /** when the user is redirected from paypal back to your site **/
        $execution = new PaymentExecution();
        $execution->setPayerId(Input::get('PayerID'));
        /**Execute the payment **/
        $result = $payment->execute($execution, $this->_api_context);
        /** dd($result);exit; /** DEBUG RESULT, remove it later **/
        if ($result->getState() == 'approved') { 
            
            /** it's all right **/
            /** Here Write your database logic like that insert record or value in database if you want **/

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

		return Redirect::route('paywithpaypal');
    }
}

Step : 7 Create view file

Now, we are create one resources/views/paywithpaypal.blade.php for display paypal form

@extends('layouts.app')

@section('content')
<div >
    <div >
        <div >
            <div >
                @if ($message = Session::get('success'))
                <div >
                    <button type="button"  data-dismiss="alert" aria-hidden="true"></button>
                    {!! $message !!}
                </div>
                <?php Session::forget('success');?>
                @endif

                @if ($message = Session::get('error'))
                <div >
                    <button type="button"  data-dismiss="alert" aria-hidden="true"></button>
                    {!! $message !!}
                </div>
                <?php Session::forget('error');?>
                @endif
                <div >Paywith Paypal</div>
                <div >
                    <form  method="POST" id="payment-form" role="form" action="{!! URL::route('addmoney.paypal') !!}" >
                        {{ csrf_field() }}

                        <div >
                            <label for="amount" >Amount</label>

                            <div >
                                <input id="amount" type="text"  name="amount" value="{{ old('amount') }}" autofocus>

                                @if ($errors->has('amount'))
                                    <span >
                                        <strong>{{ $errors->first('amount') }}</strong>
                                    </span>
                                @endif
                            </div>
                        </div>
                        
                        <div >
                            <div >
                                <button type="submit" >
                                    Paywith Paypal
                                </button>
                            </div>
                        </div>
                    </form>
                </div>
            </div>
        </div>
    </div>
</div>
