This is the main reference page for the WoW UI Lua API available to user Macros and AddOns. This is the API available during normal game play. See also WoW Glue API.

Introduction Edit

The World of Warcraft API, or WoW API, is a set of Lua functions and facilities provided by the Blizzard WoW Client, to allow interaction with the World of Warcraft and its user interface. The list below is incomplete, and kept up to date through user contributions. See also the an automatically-generated exhaustive list of all API functions present in the latest live client.

For beginners, WoW AddOn contains a number of very informative sources to help get you started. You can also examine the existing UI code to find examples of how the various functions are used by the default UI. Discuss any large-scale changes on the discussion page.

Reference Edit

Global API functions for WoW in Lua.

  • API types - variable value types, used here as parameters and return values.

If you're contributing documentation, please read How to edit API pages.

Function names can be prefixed with the following tags, see API notation and conventions:

  • PROTECTED - can only be called from secure code. See Protected Functions.
  • NOCOMBAT - can only be called from secure code while out of combat.
  • HW - may only be called in response to a hardware event, like from OnClick handlers.
  • UI - is implemented in Lua in FrameXML, but was important enough to appear here.
  • DEPRECATED - is planned to no longer be used, and more than likely removed in future version.
  • REMOVED - was removed from the API. should be moved from here to Removed Functions.

Calling functions via macro or command line:

/run BNSetMatureLanguageFilter(true)
/run local x=GetAccountExpansionLevel(); SendChatMessage(x)
