Magento 2 - Is it possible update payment method of order programmatically?

Question

Is there a way to update payment method of order in magento 2 via dependency Injector or Object factory without using raw sql query?

Answer 1

You need to load order instance either from order entity_id or increment_id. After that, try these code. I haven't tested these code

$payment = $order->getPayment();
$payment->setMethod('yourpaymentmethodcode');
$payment->save();
$order->save();

or

$order->getPayment()->importData(['method' => 'yourpaymentmethodcode']);
$order->save();

I hope this will help
