The World of Warcraft API, or WoW API, is a set of functions provided by Blizzard which enables you to interact and modify the World of Warcraft game through the use of addons and macros. Below is an almost complete list of every function provided by Blizzard that you can use in the creation of your addon or macro. Enjoy the list, and remember if you come across a function that is not documented, please submit it to WoWWiki so we can continue to have a complete list of functions available for your use.

Editing Notes:

Read How to edit API pages.
Please follow the standard API Notation and Conventions when editing.
When you make changes to this page, please update the function's page as well (reached by clicking its link).
Do not create stub pages without adding useful information to it. It is better that links to undocumented function remain red! If you do create a stub, tag it {{Stub/API}}.
Before making large-scale changes, discuss them on the discussion page.

Usage Notes:

Play around with the functions yourself by typing /script FunctionName(arg1,arg2,etc) into the chat edit box in WoW.
Look at how Blizzard did it by examining the existing UI.

History:

A change tracker for all of the API pages can be found here; Iriel's Wiki Change Tracker.

Notation:

UI - Means that the function is implemented in Lua in Blizzard's User Interface (FrameXML) but was considered important enough to appear here.
PROTECTED - This function can only be called from secure code. See the Protected Functions category.
REMOVED - This function has been removed from the World of Warcarft API (and should also be removed from this list). For historical purposes, see the Removed Functions category.

Global Function Groups

This is an incomplete list of the WoW APIs. It likely will never be 100% complete, as new APIs are added all the time.

Here is a complete list of all global functions: Global Function List. If a function on that list is missing from this page, it's because no-one has added it yet. Before you add functions, please see How to edit API pages.
