我在我的应用程序中使用cyberSource 集成Apple Pay 集成。我这样做是为了什么。
1- 我已经创建了商家 ID 2- 我已经在http://www.cybersource.com/
上创建了测试帐户
3- 我已经下载了适用于 iOS 的网络资源 SDK。
4-我已经设法运行使用 SDK 下载的演示应用程序。
5-当我运行演示应用程序时，我收到了这个错误。
"Transaction Details .Accepted: No .Auth Amount: (null) Error: Unknown error"
我已正确提供我的商家帐户。还有其他字段，我不确定如何获取这些值

我可以从哪里得到所有这些值。如果有人列出通过 CyberSource 进行 Apple 支付集成所涉及的所有步骤，我们将不胜感激。另外请不要将我推荐给苹果开发者，因为我已经在 Apple Developer 上阅读了有关 Apple Pay 的详细信息。
