MediaWiki has severalapplication programming interfaces (APIs).

The three most important APIs of MediaWiki are:

• theMediaWiki Action API (api.php), which is a web API that lets you read and write content of aMediaWiki wiki
• theMediaWiki PHP API, which can be used to developextensions for MediaWiki inPHP
• theMediaWiki JavaScript API (mw), which can be used to developuser scripts and gadgets to extend the MediaWiki user interface

Note that the MediaWiki Action API and the MediaWiki JavaScript API are both modular: both can be extended by extensions, so the available API modules can differ from wiki to wiki.^[1]While the API modules built intoMediaWiki Core are available in most MediaWiki wikis, built-in Action API modulescan also be disabled.

Within the context of the MediaWiki website the Action API can be accessed from JavaScript via themw.Api JavaScript API.(mw.ForeignApi for allowed cross-site requests, e.g. between WMF wikis.)For libraries to access the MediaWiki Action API from your favorite programming language, seeAPI:Client code.
