programatically cancel the order using order id - Magento 2

Question

My requirement is programatically change the order status to Canceled by using order id.

How to achieve this?

Answer 1

Even though using the OrderFactory would work, save and load methods are deprecated soon, you should use service contracts instead.

So you can use Magento/Sales/Api/OrderManagementInterface:

First inject an instance in your class constructor:

protected $orderManagement;

public function __construct(
    ...
    \Magento\Sales\Api\OrderManagementInterface $orderManagement,
    ....
) {
    ....
    $this->orderManagement = $orderManagement;
    ....
}

Then use the following:

$this->orderManagement->cancel($orderId);

Answer 2

use \Magento\Sales\Model\OrderFactory by injecting in the constructor, like below : to cancel the order programmatically

protected $_orderFactory;

public function __construct(
     \Magento\Sales\Model\OrderFactory $orderFactory
){
$this->_orderFactory = $orderFactory;
}

public function execute()
{
    $orderId = '1234543343'; // your order id
    $order = $this->_orderFactory->create()->load($orderId);
    $order->cancel()->save();   
}
