使用 WooCommerce Rest API 创建带有优惠券行的订单

问题描述

我们正在尝试使用 woo commerce API 创建订单并应用优惠券代码，如 woo commerce 文档中所述。以下是我们尝试通过 API 请求发送的 JSON。

{
"order":{
"payment_details":{"method_id":"cash","method_title":"cash","paid":false},"billing_address":{"first_name":"kamran","last_name":"masud","company":null,"address_1":"dubai dubai - United arab Emirates","address_2":null,"city":null,"state":null,"postcode":null,"country":null,"email":null,"phone":"541234566"},"shipping_address":{"first_name":"kamran","country":null},"customer_id":116,"line_items":[
    {"product_id":11734,"variation_id":0,"quantity":108,"total":"3834"},{"product_id":10893,"quantity":1,"total":"206.56"},{"product_id":11872,"total":"41.49"},{"product_id":11866,"total":"53.17"},{"product_id":11865,{"product_id":11965,"total":"47.81"},{"product_id":11626,"total":"323.73"},{"product_id":11927,"total":"144.3"}],"shipping_lines":[],"fee_lines":[
    {"id":0,"title":"Shipping :","tax_class":null,"total":"0","total_tax":null}
    ],"coupon_lines":[
    {
    "code":"fixedcart10","discount":"80","Meta_data":[
        {
            "key":"coupon_data","value":[
            {
                "id":"168026","code":"fixedcart10","amount":"10"
            }
            ]
        }
    ]
    }
],"discount_total":null,"shipping_total":null,"total":null,"status":"processing"}}

优惠券按照它未在创建的订单中应用的订单进行处理。以下是创建的订单的屏幕截图。

任何帮助将不胜感激。 谢谢

解决方法

我认为，因为您手动传递了“总”值，所以它会覆盖 WooCommerce 通常应用于优惠券的自动计算。如果您只传递 product_id、variation_id 和数量，应该没问题。

但是，如果您要更新 WooCommerce 订单上的 line_items，则问题会更大一些，因为折扣是根据更新时传递的 sub_total（折扣前）和 total（折扣后）值计算得出的。
