C# 创建帐单计划出错，请求格式不正确

我正在尝试创建一个账单计划，请求如下。（它是有效的JSON）并且我已经检查了请求，并且根据PayPal上给出的示例请求似乎是正确的（尽管如此，我已经尝试使用股票示例，但它不起作用

我得到的答复是：

据我所知，请求是正确的，我正在验证，我有正确的URL，有人发现问题是什么吗？

你有

autobill\u amount

，它应该是

auto\u bill\u amount

。你也有

initial\u amount\u fail\u action

而且应该是

initial\u fail\u amount\u action

对，它是我的错误是没有将周期设置为0，因为这是一个持续付款，直到有人取消它，它应该是0而不是12

因此，已更正的请求（有效）

修正了这一点，同时也修正了初始金额失败操作的错误，所以也修正了这一点，但仍然失败
