如何更新 Paypal 订单的税务信息？

Question

我正在使用 C# .net Core MVC，而对于 Paypal V2，我正在使用 https://github.com/paypal/Checkout-NET-SDK

在用户通过贝宝登录和批准后（在最终订单提交之前），我无法更新订单的税务信息。

我使用以下方法创建了订单

var request = new OrdersCreateRequest();
request.Prefer("return=representation");
request.RequestBody(order);
response = await client().Execute(request);
var statusCode = response.StatusCode;
Order result = response.Result<Order>();

然后控制转到 PayPal 并要求用户在 Paypal 登录。用户登录并单击 Paypal 上的“继续”，控件返回到我的应用程序。

此时，我需要按顺序更新税务信息，但不知道该怎么做。我正在查看以下链接以获取帮助。

https://developer.paypal.com/docs/checkout/integration-features/update-order-details/

https://developer.paypal.com/docs/api/orders/v2#orders_patch

所以我查看了补丁订单来更新税收。我在 c# 中使用以下补丁代码尝试了“OrdersPatchRequest”

 new Patch<Object>
 {
     Op= "replace",
     Path= "/purchase_units/@reference_id=='default'/amount",
     Value ="{\"breakdown\":{\"item_total\":{\"currency_code\":\"USD\",\"value\":\"1\"},\"shipping\":{\"currency_code\":\"USD\",\"value\":\"3\"},\"tax_total\":{\"currency_code\":\"USD\",\"value\":\"2\"}},\"currency_code\":\"USD\",\"value\":\"6\"}"
 }

Patch 值的格式如下所示

{
    "breakdown":
    {
        "item_total":{"currency_code":"USD","value":"1"},
        "shipping":{"currency_code":"USD","value":"3"},
        "tax_total":{"currency_code":"USD","value":"2"}
    },
    "currency_code":"USD",
    "value":"6"
}

但由于以下错误而失败

{"name":"INVALID_REQUEST","details":[{"field":"/purchase_units/@reference_id=='default'/amount","value":"{\"breakdown\":{\"item_total\":{\"currency_code\":\"USD\",\"value\":\"1\"},\"shipping\":{\"currency_code\":\"USD\",\"value\":\"3\"},\"tax_total\":{\"currency_code\":\"USD\",\"value\":\"2\"}},\"currency_code\":\"USD\",\"value\":\"6\"}","location":"body","issue":"INVALID_PARAMETER_VALUE","description":"The value of a field is invalid."}],"message":"Request is not well-formed, syntactically incorrect, or violates schema.","debug_id":"1879d34e23fc4","links":[{"href":"https://developer.paypal.com/docs/api/orders/v2/#error-INVALID_PARAMETER_VALUE","rel":"information_link","method":"GET"}]}

知道为什么它会失败吗？请帮忙。

（*上面更新的补丁值和错误消息）

你的补丁值：

"{\"breakdown\":{\"item_total\":{\"currency_code\":\"USD\",\"value\":\"1\"},\"tax_total\":\"USD\",\"value\":\"2\"},\"shipping\":{\"currency_code\":\"USD\",\"value\":\"3\"}},\"currency_code\":\"USD\",\"value\":\"6\"}"

更清晰地呈现为：

{
    "breakdown": {
        "item_total": {
            "currency_code": "USD",
            "value": "1"
        },
        "tax_total": "USD",
        "value": "2"
    },
    "shipping": {
        "currency_code": "USD",
        "value": "3"
    }
    }, "currency_code": "USD", "value": "6"
}

如您所见，这是无效的，因此出现错误
