忽略Paypal智能按钮tax get

Question

我正在我们的商店中实现PayPal智能按钮开发工具包。javascript发送到https://www.sandbox.paypal.com/v2/checkout/orders的有效负载如下所示：

{
   "reference_id":"XYZ",
   "description":"Fonts bought from hobo typefaces",
   "custom_id":"XYZ",
   "soft_descriptor":"Soft",
   "redirect_urls":{
      "return_url":"https://dev.hobo-typefaces.com/checkout",
      "cancel_url":"https://dev.hobo-typefaces.com/cancel"
   },
   "amount":{
      "currency_code":"EUR",
      "total":"378.00",
      "shipping":0,
      "value":"360.00",
      "tax":"18.00",
      "breakdown":{
         "item_total":{
            "currency_code":"EUR",
            "subtotal":"360.00",
            "value":"360.00",
            "total":"378.00",
            "shipping":0,
            "tax":"18.00"
         }
      }
   },
   "items":[
      {
         "name":"Rosart Regular",
         "sku":"Rosart Regular",
         "unit_amount":{
            "currency_code":"EUR",
            "value":"60.00"
         },
         "quantity":"1"
      },
      {
         "name":"Rosart RegularItalic",
         "sku":"Rosart RegularItalic",
         "unit_amount":{
            "currency_code":"EUR",
            "value":"60.00"
         },
         "quantity":"1"
      },
      {
         "name":"Rosart MediumItalic",
         "sku":"Rosart MediumItalic",
         "unit_amount":{
            "currency_code":"EUR",
            "value":"60.00"
         },
         "quantity":"1"
      },
      {
         "name":"Rosart Medium",
         "sku":"Rosart Medium",
         "unit_amount":{
            "currency_code":"EUR",
            "value":"60.00"
         },
         "quantity":"1"
      },
      {
         "name":"Rosart Semibold",
         "sku":"Rosart Semibold",
         "unit_amount":{
            "currency_code":"EUR",
            "value":"60.00"
         },
         "quantity":"1"
      },
      {
         "name":"Rosart SemiboldItalic",
         "sku":"Rosart SemiboldItalic",
         "unit_amount":{
            "currency_code":"EUR",
            "value":"60.00"
         },
         "quantity":"1"
      }
   ]
}

当结账流程正常工作时，税收被忽略，贝宝计算出360欧元。不幸的是，我无法用paypal文档解决这个问题。我不确定的是amount.value、amount.total和breakdown数组中的相同。

如果有人能帮我解释为什么我的税被忽略了，我将不胜感激。

您没有在purchase_units数组及其项数组中传递有效的tax对象。
