We are currently connecting to seperate 3 marketplace apps within our zoom account. 1 for ZCC 1 for ZMeetings 1 for Zoom Phone. Each market place app is setup for Websocket events. When we connect to the websocket URL for the first market place app, we get a successful connection, when we. connect the the 2nd websocket url (while the 1st is still active)…we get an error in the connection “Connected in another place” Is there a limit to how many websocket connections you can have in an account? If so what limits? To recieve websocket events for all 3 services, is the recommendation to use a single marketplace app that supports ALL 3 services? ---

Hi @ojus.zoom can you please help this developer with their use case? ---

I’ve received an event: ```auto { "module": "close_connection", "success": "True", "content": "Connected in another place", "header": {} ... } ``` Same questions here: How often can you subscribe to a WebSocket? Does it matter if you have another (new) OAuth token? How can I scale my service to listen to WebSocket events if I can only establish one connection? Any insight or recommendations are appreciated. ---

@j.c.novoa_zoom @intropy thanks for bringing this to our attention. typically for a given WebSocket subscription you can only open one subscription at a time. If you are saying that you have independent websocket subscriptions and they aren’t running concurrently, then this is a bug. Can you please confirm? ---

Right now, I have one wss:// endpoint in one Zoom App. The service subscribes to it fine. As soon as a second instance tries to subscribe to the same endpoint (but with a different token) the first connection gets closed. I guess it depends on what is meant by “independent subscription”. I was falsely under the impression both subscriptions would be able to receive events or that there would be some sort of round-robin on who will get an event on multiple subscriptions. My only option to achieve some redundancy and fault tolerance is to create a second identical wss:// endpoint. Am I right with this assumption @ojus.zoom? ---
