使用C#.NET进行Paypal自适应支付API调用？最好使用WebServices

Question

好吧,我现在可能完全偏离正轨但是这里:

我们的"网上商店"提供两种功能,购买特定产品并将其出售给我们.如果用户可以销售或不销售后端句柄.

我决定使用Paypal的自适应支付,因为这似乎是进行这类交易的方式.我从来没有实施任何类型的商店,所以我对这个完全是绿色的.我最近才学习ASP.NET,并且在转向这种开发之前主要开发了游戏.HTTP对我来说还是有些神奇的嘿嘿......

我可能会感到困惑,但我认为paypal提供了一个带有自适应支付API的网络服务.我谦虚的要求:一个好心的人想要分享一个用C#.NET实现自适应支付API调用的例子.如果他们不提供它作为web服务我可能会发现它是一个自定义.dll或其他东西.

任何提示和示例都非常感谢!谢谢阅读

这是他们的xml api.我还没有使用vs.net中自动生成的代理来使用他们的web服务.另外请记住,您必须为api信息,买方,卖方等声明常量或变量.

        // API endpoint for the Refund call in the Sandbox
        string sAPIEndpoint = "https://svcs.sandbox.paypal.com/AdaptivePayments/Pay";

        // supply your own sandbox accounts for receiver and sender


        string sTrackingID = System.Guid.NewGuid().ToString();
