Question

我花了将近一天时间试图解决这个问题，并希望得到任何提示或指导让这个该死的东西起作用！我的SetExpressCheckOut和GetExpressCheckOut函数正常工作，但我从PayPal获取对象..

但最后一步DoExpressCheckOut失败并显示以下错误消息：“您没有权限进行此API调用”因此它无法成为我的凭据，因为我在执行Set和Get调用时使用了相同的内容。

我有标准的PayPal帐户（不是专业版）我正在使用实时终点：https://api-3t.paypal.com/2.0/ 并通过API用户名/密码/签名

连接

我到处寻找是否有特定的API权限可以在PayPal上配置，但我没有运气......

这是代码。我很感激帮助......

public bool DoExpressCheckout(string token)
        {
            var getDetailsResponse = new GetExpressCheckoutDetailsResponseType();
            var getDetailsRequestType = new GetExpressCheckoutDetailsRequestType();
            var getDetailsReq = new GetExpressCheckoutDetailsReq();
            getDetailsRequestType.Version = GetVersionOrDefault();
            getDetailsRequestType.Token = token;
            getDetailsReq.GetExpressCheckoutDetailsRequest = getDetailsRequestType;

            var requestType = new DoExpressCheckoutPaymentRequestType();
            requestType.Version = GetVersionOrDefault(); // 109

             try
            {
                var type2 = new CustomSecurityHeaderType
                {
                    Credentials = new UserIdPasswordType()
                    {
                        Username = ConfigurationManager.AppSettings["PAYPAL_API_USERNAME"],
                        Password = ConfigurationManager.AppSettings["PAYPAL_API_PASSWORD"],
                        Signature = ConfigurationManager.AppSettings["PAYPAL_API_SIGNATURE"],
                    }

我知道它必须是愚蠢的东西！这是答案
CustomSecurityHeaderType ..我正在重复使用GetDetails和DoExpressCheckout调用。用户/通行证/签名信息在第一次通话时清除，当发送到paypalAAInt.DoExpressCheckoutPayment时它是空的。好悲伤。

PayPal C＃DoExpressCheckOut身份验证错误：10002
