how to update order status using API in ebay?

how to update order status using php api on ebay?

from Active to Completed, from Active to Cancelled, from Completed to Active, from Cancelled to Active

I tried to change order status from active to completed with following code.

    $service = new \DTS\eBaySDK\Trading\Services\TradingService([
        'credentials' => $ebay_info['credentials'],
        'sandbox'     => ($sandbox == 1 ? true: false),
        'siteId'      => $siteId
    ]);
    
    $request = new \DTS\eBaySDK\Trading\Types\CompleteSaleRequestType();
    $request->RequesterCredentials = new \DTS\eBaySDK\Trading\Types\CustomSecurityHeaderType();
    $request->RequesterCredentials->eBayAuthToken = $ebay_info['authToken'];

    **$request->Shipped = true;
    $request->Paid = true;**
    $request->OrderID = $orderID;

    $response = $service->CompleteSale($request);

I have set paid & shipped, but it is still "active". I am using following php ebay api https://github.com/davidtsadler/ebay-sdk-examples

how can I change order status easily using api?
