Q:

Podio webhook unverified

I created an app a year ago and verified all needed webhooks.
December 14th 2016, some webhooks became unverified, despite of the fact that they were created and valided a year ago. I looked into Podio's status page, nothing happened that day.
I'm the only administrator of the target app and nothing changed since I created the app.
I wrote to support, but the given answer was not helpful.
Anyone had this weird issue or an explaination?

A:

Hook might be un-validated if your service was too slow or down. Here is quote from https://developers.podio.com/doc/hooks 

The hook must respond with a 2xx status code. If the status code is
  different from 2xx more than 50 consecutive times the hook will return
  to being unverified and will have to be verified again to be active.
  Additionally, your hook may return to unverified if you do not send
  responses in a timely manner. You should handle any heavy processing
  asynchronously.
