You’ve always been able to send messages to HipChat rooms via the API but now you can read them back out as well. Just use the new rooms/history method.

Note that this isn’t a streaming API and that there is a delay of about a minute before sent messages will be available using this method. If you are hoping to build a bot or some other real-time interaction drop us a note and let us know that you’d like to help test our upcoming XMPP support.
