As of now I’m working on an App which hasn’t been published yet (I plan to send the request of approval soon) (even though it has a shareable URL) but I don’t manage to trigger the webhook (e.g.: by uninstalling the App from the list of **installed apps** ), which prevents me from testing end-to-end our cleanup process.

Notes:

- Upon install no error message is shown nor feedback is given: the App gets un-installed but my back-end server doesn’t receive any notificaton.
- The App is a OAuth App.
- The URL of the Deauthorization Notfication has been added in the Whitelist

Questions:

- does the App needs to already be in the Marketplace for the Deauthorization Notification to work (that would be strange imho)?
- Are there additional steps which needs to be executed for making the Deauthorization Notification operative?
