Currently there is new and improved hooks documentation available.

If you aren't familiar with what I mean by hooks, this is a feature of cPanel that allow you to run custom code a part of an API call (CustomEventHandler) or after an API call (function hooks). This is a *really* powerful feature that can be used as part of building password traps, integrating with remote systems, etc.

I advise checking them out, if you have any suggestions regarding improving these docs, please let me know so that we can update them.
