MailChimp表单未将用户注册为待处理状态，直到他们通过电子邮件确认

Question

我正在尝试将我的应用用户列表与在MailChimp上订阅的用户同步。

我们正在使用带有Rails 4的Gibbon gem。一切正常，我可以根据用户的电子邮件地址查看用户的状态，并确定他们是订阅，待处理还是无。用户可以通过指向MailChimp在线表单的链接进行注册，也可以通过选中我们的网络应用程序中的选择框进行注册。

问题是，如果用户通过MailChimp链接进行订阅，则MailChimp API不会将其识别为待处理。因此，我们的应用程序收到的是nil，而不是＆＃34; pending＆＃34;如果他们通过复选框注册，会发生什么。

由于应用收到回复nil，它会向用户表明他们应该选中该框以注册awk的简报，因为他们已经注册了一次。

除此之外，如果用户选中已经直接使用MailChimp注册的方框，则由于MailChimp已经拥有该电子邮件地址，因此会被400错误拒绝。

我的目标是在MailChimp上订阅，待定等用户时能够在应用中准确反映。

错误和完整跟踪如下：
