Hello,
I am trying to add new URL in multiple Webiste/store for Checkout page.
$cart = $objectManager->get('\Magento\Checkout\Model\Cart');
$productRepository = $objectManager->create('Magento\Catalog\Api\ProductRepositoryInterface');
$params = array(
'product' => '435',
'qty' => '1',
);
$_product = $productRepository->getById('435');
$cart->addProduct($_product, $params);
$cart->save();
Thanks
