HipChat XMPP Documentation
==========================

HipChat is, at its core, an XMPP_ server. XMPP (eXtensible Messaging and
Presence Protocol) is a — you guessed it — extensible protocol for sending
messages between devices, most commonly used for instant messaging. XMPP itself
(including XMPP IM, the instant messaging part of the spec) is maintained by
the IETF.  However, a separate body, the `XSF`_ has been formed to standardize
the extension ecosystem that has built up around XMPP. HipChat supports a
number of common XMPP specifications and extensions including:

- `RFC 6120`_: XMPP Core
- `RFC 6121`_: XMPP IM
- `XEP-0045`_: Multi-User Chat.

HipChat also supports a number of custom extensions, which can be used by
HipChat clients, XMPP bots, and regular clients to better interoperate with the
HipChat ecosystem. These custom extensions (and modifications to some existing
extensions) are documented here.
