API webhook not being called

Question

I have a Dropbox app setup to call a webhook URL to issue update notifications. This was all working until a few days ago but has now stopped working. As far as I can tell everything is setup correctly:

* The app is registered with my account using OAuth;

* I can access files in the app folder for my account over the API when I manually initiate an update;

* I've tried removing and reregistering the webhook URL - the challenge request is received and accepted, but the same URL never receives any notifications when files are updated in the app folder.

Any ideas what the problem could be?

So, this was because of an error in the webhook handler. The error didn't happen when I tested the webhook directly, and I could only see the error in the app dashboard when I rechecked it 20 minutes ago. Problem is fixed now!
