I have multiple private channels to subscribe and each channels goes through pusher authentication process. I want to know that it is possible to call pusher authentication one time for all private channels.
Update: This is now possible via a plugin: https://github.com/pusher/pusher-js#batching-auth-requests-aka-multi-auth
This is a feature that has been requested a number of times (I used to work for Pusher and handle the majority of support requests). However, it's something that you cannot presently do with any of the Pusher client libraries.
I'd recommend that you contact Pusher support and let them know you require this feature and why (probably because you're subscribing to many channels and right now this results to a high number of HTTP calls to your auth endpoint).
