单笔交易"Only single payment transaction currently supported"

Question

我是PayPal集成的新手，我正在尝试创建第一笔付款，我通过他们的模拟器（https://devtools-paypal.com/apiexplorer/PayPalRestAPIs 向PayPal Rest API 发送以下请求：

{
"intent": "sale",
"payer": {
    "payment_method": "paypal",
    "funding_instruments": [
        {
            "credit_card": {
                "number": "5277726581534042",
                "type": "mastercard",
                "expire_month": "9",
                "expire_year": "2018",
                "links": [
                    {
                        "targetSchema": {
                            "readonly": "true"
                        },
                        "schema": {
                            "readonly": "true"
                        }
                    }
                ]
            }
        }
    ],
    "payer_info": {
        "email": "[e-mail]"
    }
},
"transactions": [
    {
        "amount": {
            "currency": "USD",
            "total": "10"
        },
        "payee": {
            "email": "[e-mail]"
        }
    }
],
"redirect_urls": {
    "return_url": "yandex.ru",
    "cancel_url": "google.com"
},
"links": [
    {
        "href": "http://google.com",
        "rel": "http://yandex.ru",
        "targetSchema": {
            "readonly": "true"
        },
        "schema": {
            "readonly": "true"
        }
    }
]
}

我得到的回复是：

{
"name": "VALIDATION_ERROR",
"details": [
    {
        "field": "transactions",
        "issue": "Only single payment transaction currently supported"
    }
],
"message": "Invalid request - see details",
"information_link": "https://developer.paypal.com/webapps/developer/docs/api/#VALIDATION_ERROR",
"debug_id": "08c2dc7a41f64"

}我只是不知道如何让它工作..

PayPal只是说我发送了 2 笔付款..

任何帮助将不胜感激

Answer 1

您是想用卡还是PayPal钱包付款？
也就是说，您是打算直接向卡收费，还是将用户重定向到PayPal？
在当前请求中，您将包含来自这两个选项的数据。这可能是 API 资源管理器的问题，如果这是它给你的。

试试这个：

curl -v https://api.sandbox.paypal.com/v1/payments/payment 
-H 'Content-Type:application/json' 
-H 'Authorization:Bearer EEwJ6tF9x5WCIZDYzyZGaz6Khbw7raYRIBV_WxVvgmsG' 
-d '{
  "intent":"sale",
  "redirect_urls":{
    "return_url":"http://example.com/your_redirect_url/",
    "cancel_url":"http://example.com/your_cancel_url/"
  },
  "payer":{
    "payment_method":"paypal"
  },
  "transactions":[
    {
      "amount":{
        "total":"7.47",
        "currency":"USD"
      }
    }
  ]
}'

或者对于卡付款：

curl -v https://api.sandbox.paypal.com/v1/payments/payment 
-H "Content-Type:application/json" 
-H "Authorization:Bearer EEwJ6tF9x5WCIZDYzyZGaz6Khbw7raYRIBV_WxVvgmsG" 
-d '{
  "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."
    }
  ]
}'
