at the current State the getOrders Function is not usable here's a quick example:
Code
$user = '<USER>';
$apiPassword = '<PASSWORD>';
$apiKey = '<API_KEY>';
$client = new \BillbeeDe\BillbeeAPI\Client($user, $apiPassword, $apiKey);
$orders = $client->orders()->getOrders();
var_dump($orders);
and the Results are:
Results
object(BillbeeDe\BillbeeAPI\Response\GetOrdersResponse)#96 (4) { ["data"]=> array(0) { } ["paging"]=> NULL ["errorMessage"]=> NULL ["errorCode"]=> int(0) }
Same Request with Postman and same Credentials:
Postman

Technical View
a deeper look into the Code shows that the data is being retrieved but is not mapped correctly into the OrderResponse interface. Used PHP Version 8.0
