PayPal API with Laravel - Updating of data

Question

I'm trying to implement the API of PayPal payment with Laravel 5.1. But when I log in to 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]);

         $patchReplace = new Patch();
         $patchReplace->setOp('add')
                    ->setPath('/transactions/0/item_list/shipping_address')
                    ->setValue(json_decode('{
                        "line1": "345 Lark Ave",
                        "city": "Montreal",

                        "country_code": "CA"
                    }'));

         $patchRequest = (new PatchRequest())->setPatches([$patchReplace]);


        try{

            $payment->create($this->_api_context);
            $payment->update($patchRequest, $this->_api_context);

        } catch(\Palpal\Exception\PPConnectionException $e){

            if(\Config::get('app.debug')){
                return redirect()

        }

        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()
                ->route('bookstore.shipping')
                ->with('danger', 'Unknown error occured.');
    }

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

        if(empty(Input::get('PayerID')) || empty(Input::get('token'))){
            return redirect()
                    ->route('bookstore.shipping')

I also reviewed this link but it seems like it cannot answer my problem. Also, what if the country has a province? How can we add that?

Answer 1

After you have created the payment, try updating the address as shown in this example.

$paymentId = $createdPayment->getId();

$patch = new \PayPal\Api\Patch();
$patch->setOp('add')
    ->setPath('/transactions/0/item_list/shipping_address')
    ->setValue([
        "recipient_name" => "Gruneberg, Anna",
        "line1" => "52 N Main St",
        "city" => "San Jose",
        "state" => "CA",
        "postal_code" => "95112",
        "country_code" => "US"
    ]);

$patchRequest = new \PayPal\Api\PatchRequest();
$patchRequest->setPatches([$patch]);
$result = $createdPayment->update($patchRequest, $apiContext);
