Hi @112496 One API key with one access token = one WebSocket is not a blocker am seeing in any case. We had given more than a month to migrate and also an alternative environment was made available to make the transition smooth.
An Access token is just to access a valid session and it can be reused for all requests. Also same goes with websockets where all the updates are sent and you don't need a new socket for some other activities. You would need to rethink on the way to structure your code for better execution.
