I want to make some changes if the chosen payment method is COD. On existing WC_Order i have used
($order->payment_method_title == 'Cash On Delivery' ? ... : ... );
to retrieve the title. But i would like to check against the id (cod) because the title string gets translated to different languages which doesn't make it a good solution.
Is there a way to retrieve the id on a WC_Order in woocommerce?
