@alexewsv For subscription is a little different. On the browser we can't set headers when creating a websocket connection. You can check this page for a more detailed explanation on it. So, for sending a token to a subscription you could send it as the initial parameters of the subscription. This is showed on this example. On the example we register the on_connection_init callback function. This function will be called when a new connections is created and will check the token
