有人可以提供在ASP.NET中执行此操作的示例。我们想做一些MailCHimp - 内部数据库同步并计划使用webhooks功能执行此操作，但我们无法让它工作。当有人取消订阅邮件黑猩猩时，我们希望使用网络钩子来同步数据。
要解决的另一件事是安全性。我们如何保护此页面不被恶意用户访问？

这是一段适合我们的代码。这很简单，但它确实需要我们进行一些实验才能让它发挥作用。
if (Request.Form["type"] != null && Request.Form["type"] == "unsubscribe")
{
string email = Request.Form["data[merges][EMAIL]"];
//now you can do insert/update data in your local database
}
查看API文档以获取更多详细信息http://apidocs.mailchimp.com/webhooks/
关于安全性，你可以做很多事情，但这取决于你想要的深度。我建议的一件事是检查您的IIS日志，找到邮件黑猩猩使用哪个IP地址/用户代理来触发Web挂钩，然后阻止此页面除此之外的所有其他IP地址。你可以采取其他措施来额外保护这一点，例如使用不容易猜到的页面名称（f3jijselife.aspx远远优于webhooks.aspx）

我正在使用C＃WebAPI，我的解决方案是使用POST MailChimp的主体发送的FormDataCollection对象和webhook。
using System.Net.Http.Formatting;
[HttpPost]
[Route("mailchimp/subscriber")]
public IHttpActionResult Post([FromBody] FormDataCollection data)
{
if (data != null)
{
string type = data.Get("type");
if (!string.IsNullOrWhiteSpace(type))
{
string listId = data.Get("data[list_id]");
string id = data.Get("data[id]");
string firstName = data.Get("data[merges][FNAME]");
string lastName = data.Get("data[merges][LNAME]");
string email = data.Get("data[email]");
if (!string.IsNullOrWhiteSpace(email))
{
// Do something with the subscriber
}
}
}
}

我完全支持詹姆斯的答案。
然而，当我自己尝试实现webhook时，我发现你还需要实现一个GET方法，以便甚至能够在MailChimp中创建webhook。
这对我有用：
[HttpGet]
[HttpOptions]
public HttpResponseMessage Get()
{
return Request.CreateResponse(HttpStatusCode.OK);
}
