多笔交易

Question

如何在Paypal中进行多笔交易。

我尝试使用以下JSON请求

{
  "intent": "sale",
  "payer": {
    "payment_method": "credit_card",
    "funding_instruments": [
      {
        "credit_card": {
          "number": "5500005555555559",
          "type": "mastercard",
          "expire_month": 12,
          "expire_year": 2018,
          "cvv2": 111,
          "first_name": "Joe",
          "last_name": "Shopper"
        }
      }
    ]
  },
  "transactions": [
    {
      "amount": {
        "total": "7.47",
        "currency": "USD"
      },
      "description": "This is the payment transaction description."
    },{
      "amount": {
        "total": "9.71",
        "currency": "USD"
      },
      "description": "This is the payment transaction description 2."
    }
  ]
}

但它给出了以下回复

{   “name”：“VALIDATION_ERROR”，   “细节”： [     {       “字段”：“交易”，       “问题”：“目前仅支持单笔付款交易”     }   ]   “message”：“请求无效 - 请参阅详细信息”，   “information_link”：“https://developer.paypal.com/webapps/developer/docs/api/#VALIDATION_ERROR”，   “debug_id”：“b18a0e6fdfe1d” }
