问题描述
Noobish问题：你应该以某种方式回应实时更新（RTU）吗？继续获得与已退款的相同争议的RTU。那么，应该在RTU回调中回应一些东西？刚刚通过我可以找到的所有文件（再次），似乎没有找到任何响应。
Noobish question: Are you supposed to respond to realtime updates (RTUs) somehow? Keep getting RTUs on the same dispute which FB has already refunded. So, should one echo something in the RTU callback? Just been through all the documentation I can find (again) and can't seem to find anything on response.
推荐答案
是的，您需要返回200.内容类型或响应正文无关紧要。还有一件事情会导致Facebook重试回叫，直到收到200，所以你会得到很多垃圾邮件
Yes, you need to return a 200. The content type or response body do not matter. Anything else results in Facebook retrying the callback until a 200 is received, so you'll get lots of spam
