The remote server returned an error: (401) Unauthorized with paypal

Question

场景

在这里，我使用 paypal 使用信用卡直接付款，我将 CC 详细信息存储在 paypal 帐户和 paypal return 信用卡令牌中，我正在保存此令牌我的数据库中的数字进行直接付款，并且通过使用此令牌，我可以使用沙盒帐户进行直接付款但是当我对真实帐户执行相同操作时，会出现如下错误。

The remote server returned an error: (401) Unauthorized.

这是我的错误响应：

{"name":"UNAUTHORIZED_PAYMENT","message":"Unauthorized payment.","information_link":"https://developer.paypal.com/webapps/developer/docs/api/#UNAUTHORIZED_PAYMENT","debug_id":"be6ad614a3843"}

这是代码

try
{
    Dictionary<string, string> sdkConfig = new Dictionary<string, string>();
    sdkConfig.Add("mode", "live");
    string accessToken = new OAuthTokenCredential(PayPalConfig.PaypalClientId, PayPalConfig.PaypalClientSecret, sdkConfig).GetAccessToken();
    APIContext apiContext = new APIContext(accessToken);
    apiContext.Config = sdkConfig;

    // Items within a transaction.
    var item = new Item()
    {
        name = "Item Name",
        currency = "USD",
        price = "1",
        quantity = "8",
        sku = "sku"
    };

    // A resource representing a credit card that can be used to fund a payment.
    var credCardToken = new CreditCardToken()
    {
        credit_card_id = "Here CC Token Number"
    };

    var amnt = new Amount()
    {
       currency = "USD",
       total = "10",
       details = new Details()
       {
           shipping = "1",
           subtotal = "8",
           tax = "1"
       }
   };

   // A transaction defines the contract of a
   // payment - what is the payment for and who
   // is fulfilling it. 
   var tran = new Transaction()
   {
      amount = amnt,
      description = "This is the payment transaction description.",
      item_list = new ItemList() { items = new List<Item>() { item } }
   };

   // A resource representing a Payer's funding instrument. For stored credit card payments, set the CreditCardToken field on this object.
   var fundInstrument = new FundingInstrument()
   {
       credit_card_token = credCardToken
   };

   // A Payment Resource; create one using the above types and intent as 'sale'
   var pymnt = new Payment()
   {
       intent = "sale",
       payer = new Payer()
       {
           funding_instruments = new List<FundingInstrument>() { fundInstrument },
           payment_method = "credit_card"
       },
       transactions = new List<Transaction>() { tran }
    };

    // Create a payment using a valid APIContext
    var createdPayment = pymnt.Create(apiContext);
}
catch (Exception ex)
{
    throw;
}

如果有人对此问题有任何想法，请告诉我。或者建议我哪里做错了。

Answer 1

很高兴一个月后解决了这个问题，

原因： 我的代码方面没有问题，一切都是正确的，但 Paypal 方面有问题。在“我的帐户”中，我无法更改 直接信用卡 权限选项 'enable to green tick'。但现在在与 Paypal team.You 的长时间讨论后解决了，如下图所示。希望这个答案也能帮助其他人。
