Webhook does not trigger

Hi codeAndchill​ 

There are a few reasons you may not be seeing webhook notifications:

1. Have you "linked" or "connected" or "authorized" the app to your account, before making the file changes? Webhook notifications will only be sent for changes in accounts that are connected to the app. When you create a Dropbox API app as a developer, it is not automatically connected to your account as if you were an end-user of the app. You will need to connect to it, as covered in the OAuth guide.
2. Are you making changes in the same account that you've linked to the app? Similar to the above, make sure you're making changes in the correct account.
3. If your app is registered for the "app folder" permission, are you making changes in the special app folder created for the app? Webhook notifications will only be sent for changes that the app can access, so Dropbox won't send webhook notifications to an app folder app for changes outside its app folder.
4. Was your app configured with the "files.metadata.read" scope before you connected it to your account? For scoped apps, webhooks will only be sent for apps authorized with that scope. If you only added that scope after connecting the app to your account, you'll need to re-authorize the app to access your account with that scope enabled.
5. Are you sure you've properly configured your server to handle webhook notifications at your specified URL? It may be helpful to add some logging along that code path to see where it may be breaking down.
