Hi everyone,
I'm having some issues creating and redirecting a user to a cart from an external catalogue.
I'm using an interactive catalogue (external website) where a client can add products to a temporary cart. When clicking checkout on this external catalogue, XML is posted to my controller (on my Magento 2.4.0 website).
- I'm able to grab the correct information from the XML
- I think that I'm able to build the cart (Debugging from getQuote(), I see my items correctly)
But when the user is redirected to the /checkout/cart page, the cart is empty.
My guess is that I'm building the cart in a different session ID?
During debugging, I rewrote almost all my code to use a solution proposed in
another post , and tweaked it to my needs and some errors I was getting.
Here is my code :

$new = simplexml_load_string($rawdata);
$con = json_encode($new);
$newArr = json_decode($con, true);
//Build the cart
$cartitems = [];
foreach($new->lineitems->item as $item){
$product = [];
$product[] = $item->qty;
$product[] = $item->sku;
$cartitems[] = $product;
}
try {
foreach($cartitems as $citem){

$productId = $objectManager->get('Magento\Catalog\Model\Product')->getIdBySku($citem[1]);
$qty = $citem[0];
$id = $citem[1];
$params = array();
$params['qty'] = $qty;
$_product = $this->product->load($productId);
if ($_product) {
$this->cart->addProduct($_product, $params);
$this->cart->save();
}
}
$this->messageManager->addSuccess(__('Add to cart successfully.'));
}
catch (\Magento\Framework\Exception\LocalizedException $e) {
$this->messageManager->addException(
$e,
__('%1', $e->getMessage())
);
}
catch (\Exception $e) {
$this->messageManager->addException($e, __('error.'));
}
// START DEBUG
// Check what is in the cart
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$cart = $objectManager->get('\Magento\Checkout\Model\Cart');
// get quote items collection
$itemsCollection = $cart->getQuote()->getItemsCollection();
// get array of all items what can be display directly
$itemsVisible = $cart->getQuote()->getAllVisibleItems();
// get quote items array
$items = $cart->getQuote()->getAllItems();
foreach($items as $item) {
echo 'ID: '.$item->getProductId().'<br />';
echo 'Name: '.$item->getName().'<br />';
echo 'Sku: '.$item->getSku().'<br />';
echo 'Quantity: '.$item->getQty().'<br />';
echo 'Price: '.$item->getPrice().'<br />';
echo "<br />";
}
// END DEBUG
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS');
$carturl = 'https://'.$_SERVER['SERVER_NAME'].'/checkout/cart/';
header("Location: ".$carturl, true, 301);
echo $carturl;
exit;
}
}
I tried various redirection methods, but with the catalogue solution I'm using I need to output the cart URL in the browser in order to redirect correctly. Hence the echo $carturl;
Any help would be greatly appreciated 
Thank you!

I built something like that as a custom plugin for a client a few months ago based on this guys post: https://community.magento.com/t5/Magento-2-x-Programming/Adding-a-product-to-the-cart-from-an-external-site-on-Magento-2/td-p/103066
