PayPal 隐式付款错误 580001

我在实施贝宝隐式付款时遇到一些困难，不幸的是贝宝的错误消息响应中的详细信息非常有限。

这是请求：

{
    "actionType": "PAY", 
    "currencyCode": "USD", 
    "cancelUrl": "http://my_domain.com/cancel_url", 
    "returnUrl": "http://my_domain.com/return_url", 
    "requestEnvelope.errorLanguage": "en_US", 
    "requestEnvelope.detailLevel": "ReturnAll", 
    "senderEmail": "[email protected]", 
    "receiverList.receiver(0).amount": 50, 
    "receiverList.receiver(0).email": "[email protected]"
}

这是我设置的标题：

    "Content-Type", "application/json"
    "Accept-Language", "en_US"

    "X-PAYPAL-SECURITY-USERID", "username"
    "X-PAYPAL-SECURITY-PASSWORD", "pwd"                           
    "X-PAYPAL-SECURITY-SIGNATURE", "sig"                           
    "X-PAYPAL-APPLICATION-ID", "My App id"
    "X-PAYPAL-REQUEST-DATA-FORMAT", "JSON"
    "X-PAYPAL-RESPONSE-DATA-FORMAT", "JSON"

这是回应：

{
    "responseEnvelope":{
      "timestamp":"2013-04-06T12:02:41.011-07:00",
      "ack":"Failure",
      "correlationId":"3842d361b077d",
      "build":"5563463"},"error":[{
         "errorId":"580001",
        "domain":"PLATFORM",
        "subdomain":"Application",
        "severity":"Error",
        "category":"Application",
        "message":"Invalid request: {0}"
      }]
}

我刚刚遇到了完全相同的问题，但在任何地方都找不到答案。结果我使用的是 GET 请求而不是 POST 请求。奇怪的是，在他们的文档中找不到 errorId 580001。
