**Description**  
We stopped getting Deauthorization notifications to our specified endpoint url

**Which App Type (OAuth / Chatbot / JWT / Webhook)?**  
OAuth/Webhook

**How To Reproduce (If applicable)**  
Installing our app and uninstalling it does not send the deauthorized notification. I suspect we have been blacklisted because it worked yesterday? Can you please confirm.

**Additional context**  
I don’t know if its safe for me to post further information here. Can support get the client id from my account?

Hey @hunter.steele2,

Thank you for reaching out to the Zoom Developer Forum. Please confirm that there were no changes to the logic of that endpoint. Specifically, we’ll want to confirm that the endpoint is still returning a 200 OK status on receipt of the event.

If that doesn’t help, would you be able to test setting the Deauthorization URL that you’re using to something else, such as a [Request Bin](https://requestbin.com/) endpoint?

This will help us to confirm if the issue is with the current endpoint that you’re using.

Thanks,  
Max
