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-](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 ---

Hi @eladw Thanks for reaching out to the Zoom Developer Forum and sorry for the late reply here! This is the expected behavior. This event will be sent once your app is in production and one of your users deauthorizes the app. Hope this helps, Elisa ---

Actually can you try to take a look at this post? > [@SDKERR\_MODULE\_LOAD\_FAILED - Not with the demo project](https://devforum.zoom.us/t/sdkerr-module-load-failed-not-with-the-demo-project/80158/3): > > Keep getting the error : AccessViolaition : Attempted to read or write protected memory.
