Deauthorization webhook

Hi ,

I want to test the deauthorization webhook zoom sends to a url provided in the app information when user removes the app.

When removing the app from marketplace as follows in the link : https://support.zoom.us/hc/en-us/articles/4423045745037-Installing-and-uninstalling-apps-from-Marketplace-

I get no webhook even tough my site is listening and open to the entire world requests.

By the way when sending post request from postman to the same url I do get webhook.

Any thoughts ?

Thank you
