**Description** The zoom deauthorization webhook notification is not being sent when I uninstall the _production_ version of an app which hasn’t been submitted for approval yet. I can confirm there’s also no activity when testing by setting the notification URL to point to my own publically accessible webservers. **Error** The full error message or issue you are running into.

Hey @hsiung, Thanks for reaching out about this. Can you ensure that you’re installing the production instance of the app using the Publishable URL? If you are, also please double check that your Publishable URL is up to date. You can regenerate this by clicking the regenerate button under the **Submit** tab of your app: ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/a/b/ab3fcf704e20bd9a5eb135f2ffb14276c4a5b4ec.png) Once you’ve regenerated the URL, please try installing and uninstalling the app again. Let me know if you still have trouble after following these steps. Thanks! Will ---

Thanks @will.zoom it is working now after I clicked on “Regenerate”. However, I don’t think the Publishable URL I used to install the app changed since I see the same URL in my browser history. Does tapping on “Regenerate” change something on the backend for Zoom? It is my first time tapping on it. ---

Hey @hsiung, Thanks for clarifying, and glad to hear it’s working now. To clarify, the Publishable URL will need to be regenerated each time you update any fields in your app, such as deauthorization endpoint, redirect URL etc., to ensure the Publishable URL is reflecting the most up to date version of your app. Thanks, Will ---
