Php 通过rest api下订单时，Woocommerce停止客户电子邮件

我试图停止所有客户通过rest api在woocommerce下订单的电子邮件。 我并不擅长编码，但我拼凑了以下函数。我怀疑我获取订单详细信息的方式有问题

任何帮助都将不胜感激

add_action( 'woocommerce_email', 'remove_API_order_emails' );

function remove_API_order_emails( $email_class ) {
        

        // Get an instance of the WC_Order object
        $order = wc_get_order( $order_id );
        $created_via = $order->get_created_via();

        if ( $created_via = "rest-api" ) {

            /**
             * Hooks for sending emails during store events
             **/
            remove_action( 'woocommerce_low_stock_notification', array( $email_class, 'low_stock' ) );
            remove_action( 'woocommerce_no_stock_notification', array( $email_class, 'no_stock' ) );
            remove_action( 'woocommerce_product_on_backorder_notification', array( $email_class, 'backorder' ) );
            
            // New order emails
            remove_action( 'woocommerce_order_status_pending_to_processing_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );
            remove_action( 'woocommerce_order_status_pending_to_completed_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );
            remove_action( 'woocommerce_order_status_pending_to_on-hold_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );
            remove_action( 'woocommerce_order_status_failed_to_processing_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );
            remove_action( 'woocommerce_order_status_failed_to_completed_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );
            remove_action( 'woocommerce_order_status_failed_to_on-hold_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );
            
            // Processing order emails
            remove_action( 'woocommerce_order_status_pending_to_processing_notification', array( $email_class->emails['WC_Email_Customer_Processing_Order'], 'trigger' ) );
            remove_action( 'woocommerce_order_status_pending_to_on-hold_notification', array( $email_class->emails['WC_Email_Customer_Processing_Order'], 'trigger' ) );
            
            // Completed order emails
            remove_action( 'woocommerce_order_status_completed_notification', array( $email_class->emails['WC_Email_Customer_Completed_Order'], 'trigger' ) );
                
            // Note emails
            remove_action( 'woocommerce_new_customer_note_notification', array( $email_class->emails['WC_Email_Customer_Note'], 'trigger' ) );
        
        }
