Hi @jokuja, Can you confirm that you’re testing with your Production/Publishable URL when installing and then uninstalling your app? Thanks, Will ---

I am testing installation using publishable URL, but there is no publishable URL for deauthorization, therefor I am doing it from my Zoom profile → installed apps, where the app appears: [https://marketplace.zoom.us/user/installed](https://marketplace.zoom.us/user/installed) If there is any other way how to trigger “deauthorization” event please let me know. I also tried “Test the App Locally” but this doesnt trigger any events towards my API (at least not when using ngrok) ---

Hi @jokuja, You can also revoke an access\_token / deauthorize an app using this flow: > **[OAuth 2.0 - Authorization - Documentation](https://marketplace.zoom.us/docs/guides/auth/oauth#revoking)** > > OAuth with Zoom > > The Zoom API uses OAuth 2.0 to authenticate and authorize users to make requests. To set up access credentials and request scopes for y... Have you tried this? Thanks, Will ---

Thanks for this, but I want to test a scenario when users will revoke access from Zoom dashboard before having Zoom app in production. Revoking using API is not a problem. ---

Hi @jokuja, It should still be possible to test this by uninstalling the production instance of the app from the user’s dashboard in the marketplace. If you’re still seeing the empty deauthorization event, can you share an example with us by opening up a request [here](https://devsupport.zoom.us)? Please include the authorization URL that was used, the test user, and the timestamp of the event with the empty payload. Thanks, Will ---
