通过Rest API创建订单时无法加税

Question

在woocommerce中通过rest api创建订单时，我试图加税，但是它不起作用。

$order_data = [
                    'payment_method' => 'COD',
                    'payment_method_title' => 'Cash on delivery',
                    'set_paid' => true,
                    'billing' => $billing_address,
                    'shipping' => $shipping_address,
                    'line_items' => $cart_item,
                    'customer_id' => (int)$user_woocommerce_id,
                    'total' => $total_price,
                    'total_tax'=> '100',
                    'tax_lines' => [
                        'rate_code'=> 'GST',
                        'rate_id'=> 75,
                        'total_tax' => '100',
                    ],
                    'shipping_lines' => [
                        [
                            'method_id' => 'flat_rate',
                            'method_title' => 'Flat Rate',
                            'total' => $shipping_cost
                        ]
                    ]
                ];

我应该按顺序加税。
