How to use data from website to paypal shipping with laravel

I'm trying to implement the API of paypal payment with laravel 5.1. But when I login in paypal (sandbox), it uses the address I used in my account, and also it uses the name from paypal account not the data from my website. That's my problem.

I want to use the data from my website because it doesn't make sense if I enter the shipping address (for example) from my website and not using it. Please see my code below for reference (Or comment down below for some details from me).

class PaypalPaymentController extends BaseController
{

    private $_api_context;

    public function __construct(){
        $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']);
    }

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

        $price = 0;

        switch($request->get('amount')) {
            case '10 books':
                $price = 6200;
                break;
            case '20 books':
                $price = 12200;
                break;
            case '50 books':
                $price = 25200;
                break;
            default:
                return redirect()
                        ->route('bookstore.shipping')
                        ->with('danger', 'Please select the right amount of book/s.');
                break;
        }

        $item1 = new Item();
        $item1->setName($request->get('amount'))
                ->setCurrency('PHP')
                ->setQuantity(1)
                ->setPrice($price);

        $item_list = new ItemList();
        $item_list->setItems([$item1]);

        $amount = new Amount();
        $amount->setCurrency('PHP')
                ->setTotal($price);

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

        $redirect_urls = new RedirectUrls();
        $redirect_urls->setReturnUrl(route('bookstore.payment-status'))
                        ->setCancelUrl(route('bookstore.payment-status'));

        $payment = new Payment();
        $payment->setIntent('Sale')
                ->setPayer($payer)
                ->setRedirectUrls($redirect_urls)
                ->setTransactions([$transaction]);

        try{
            $payment->create($this->_api_context);
        } catch(\Palpal\Exception\PPConnectionException $e){
            if(\Config::get('app.debug')){
                return redirect()

            }

            return redirect()
                    ->route('bookstore.shipping')
                    ->with('danger', 'Some error occured, sorry for the inconvenience.');
        }

        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);
        }

        return redirect()

    }

    public function getPaymentStatus(){

        Session::forget('paypal_payment_id');

        }

        $payment = Payment::get($payment_id, $this->_api_context);
        $execution = new PaymentExecution();
        $execution->setPayerId(Input::get('PayerID'));

        $result = $payment->execute($execution, $this->_api_context);

        if($result->getState() == 'approved'){
            // Send Email
            $email_data = [
                'number_of_books' => $payment->transactions[0]->item_list->items[0]->name,
                'shipping' => [
                    'street' => $payment->payer->payer_info->shipping_address->line1,
