贝宝REST协议被取消了吗？

Question

我使用Paypal REST (java)执行定期订阅。

流程看起来是这样的，它正在工作：

• 我制定了一个计划(好)
• 我启动了一个计划(好)
• 我达成了协议(好的)
• 我使用审批链接将用户重定向到Paypal (ok)
• Paypal将用户重定向回我的站点(ok)
• 我可以执行协议(好的)

我发现，作为一个买家，我可以登录贝宝和手动取消协议任何时候。

问题是：

作为卖方，我可以看到买方x取消了他在'profile >定期付款仪表板‘中的协议，但是我如何用代码查询这些信息呢？假设我有协议Id。在“协议”对象内没有提供此类信息。

请给我指出正确的方向。谢谢

更新：

我的协议对象如下所示：

您有两个选项1:设置接收Paypal (即时支付通知)，以便他们将通知你，如果协议被取消。

他说:你可以像https://developer.paypal.com/docs/api/#retrieve-an-agreement中提到的那样检索协议细节，它会给你这样的回应
