I would like to create an app that allows a server application to write to zoom users from my company and receive messages written to by the users. I have chosen a “Server-to-Server OAuth” app for this purpose. Sending messages to users is no problem. However, I can’t find any notifications for normal chat messages? Neither via webhook nor via websocket. I can’t check the API “chat/users/me/sessions” every few seconds to see if I have received new messages? ---

As I have just discovered, polling “chat/users/me/sessions” is also not possible, as the sessions are only visible when they are active, i.e. my user for the server service has logged into the WebApp. ---

Hi @elisa.zoom it’s clear that it’s available for General Apps. However, it is not available in the same place for Server to Server-Apps… I’m pretty sure this was possible before the new build flow was implemented. ---

Any update here? We had an already working app that was ready to use and are now waiting to be able to make it work again… ---

Hi @moritz Thanks for your patience I was able to reach out to our Engineering team, and they shared with me that as chat-related webhooks contain private and sensitive information, so it requires explicit authorization from the user. So you will have to use a General app User managed type ---
