Language to use for message translations. <kbd>[[Special:ApiHelp/query+siteinfo|action=query&meta=siteinfo]]</kbd> with <kbd>siprop=languages</kbd> returns a list of language codes, or specify <kbd>user</kbd> to use the current user's language preference, or specify <kbd>content</kbd> to use this wiki's content language.

Parses content and returns parser output.

See the various prop-modules of <kbd>[[Special:ApiHelp/query|action=query]]</kbd> to get information from the current version of a page.

There are several ways to specify the text to parse:
# Specify a page or revision, using <var>$1page</var>, <var>$1pageid</var>, or <var>$1oldid</var>.
# Specify content explicitly, using <var>$1text</var>, <var>$1title</var>, and <var>$1contentmodel</var>.
# Specify only a summary to parse. <var>$1prop</var> should be given an empty value.

Modules to display help for (values of the <var>action</var> and <var>format</var> parameters, or <kbd>main</kbd>). Can specify submodules with a <kbd>+</kbd>.

This module accepts additional parameters depending on the available authentication requests. Use <kbd>[[Special:ApiHelp/query+authmanagerinfo|action=query&meta=authmanagerinfo]]</kbd> with <kbd>amirequestsfor=$1</kbd> (or a previous response from this module, if applicable) to determine the requests available and the fields that they use.

Perform a prefix search for page titles.

Despite the similarity in names, this module is not intended to be equivalent to [[Special:PrefixIndex]]; for that, see <kbd>[[Special:ApiHelp/query+allpages|action=query&list=allpages]]</kbd> with the <kbd>apprefix</kbd> parameter. The purpose of this module is similar to <kbd>[[Special:ApiHelp/opensearch|action=opensearch]]</kbd>: to take user input and provide the best-matching titles. Depending on the search engine backend, this might include typo correction, redirect avoidance, or other heuristics.

Only use these authentication requests, by the <samp>id</samp> returned from <kbd>[[Special:ApiHelp/query+authmanagerinfo|action=query&meta=authmanagerinfo]]</kbd> with <kbd>amirequestsfor=$1</kbd> or from a previous response from this module.

This is the HTML representation of the $1 format. HTML is good for debugging, but is unsuitable for application use.

Specify the <var>format</var> parameter to change the output format. To see the non-HTML representation of the $1 format, set <kbd>format=$2</kbd>.

See the [[mw:API|complete documentation]], or the [[Special:ApiHelp/main|API help]] for more information.

List ID; omit or set to <kbd>0</kbd> to use the watchlist.

The general procedure to use this module is:
# Fetch the fields available from <kbd>[[Special:ApiHelp/query+authmanagerinfo|action=query&meta=authmanagerinfo]]</kbd> with <kbd>amirequestsfor=$4</kbd>, and a <kbd>$5</kbd> token from <kbd>[[Special:ApiHelp/query+tokens|action=query&meta=tokens]]</kbd>.
# Present the fields to the user, and obtain their submission.
# Post to this module, supplying <var>$1returnurl</var> and any relevant fields.
# Check the <samp>status</samp> in the response.
#* If you received <samp>PASS</samp> or <samp>FAIL</samp>, you're done. The operation either succeeded or it didn't.
#* If you received <samp>UI</samp>, present the new fields to the user and obtain their submission. Then post to this module with <var>$1continue</var> and the relevant fields set, and repeat step 4.
#* If you received <samp>REDIRECT</samp>, direct the user to the <samp>redirecttarget</samp> and wait for the return to <var>$1returnurl</var>. Then post to this module with <var>$1continue</var> and any fields passed to the return URL, and repeat step 4.
#* If you received <samp>RESTART</samp>, that means the authentication worked but we don't have a linked user account. You might treat this as <samp>UI</samp> or as <samp>FAIL</samp>.

Message collection filters. Use <kbd>!</kbd> to negate condition. For example <kbd>!fuzzy</kbd> means list only all non-fuzzy messages. Filters are applied in the order given.
;fuzzy:Messages with fuzzy tag.
;optional:Messages which should be translated only if changes are necessary.
;ignored:Messages which are never translated.
;hastranslation:Messages which have a translation regardless if it is fuzzy or not.
;translated:Messages which have a translation which is not fuzzy.
;changed:Messages which have been translated or changed since last export.
;reviewer&#58;N:Messages where the user number <kbd>N</kbd> is among reviewers.
;last-translator&#58;N:Messages where the user number <kbd>N</kbd> is the last translator.

List of module names (values of the <var>action</var> and <var>format</var> parameters, or <kbd>main</kbd>). Can specify submodules with a <kbd>+</kbd>.

Use this authentication request, by the <samp>id</samp> returned from <kbd>[[Special:ApiHelp/query+authmanagerinfo|action=query&meta=authmanagerinfo]]</kbd> with <kbd>amirequestsfor=$1</kbd>.

Gives the ResourceLoader modules used on the page. To load, use <code>mw.loader.using()</code>. Either <kbd>jsconfigvars</kbd> or <kbd>encodedjsconfigvars</kbd> must be requested jointly with <kbd>modules</kbd>.

Revision ID to diff each revision to. Use <kbd>prev</kbd>, <kbd>next</kbd> and <kbd>cur</kbd> for the previous, next and current revision respectively.

Send an email to user <kbd>WikiSysop</kbd> with the text <kbd>Content</kbd>.

When accessing the API using a cross-domain AJAX request (CORS), use this to authenticate as the current SUL user. Use <kbd>[[Special:ApiHelp/centralauthtoken|action=centralauthtoken]]</kbd> on this wiki to retrieve the token, before making the CORS request. Each token may only be used once, and expires after 10 seconds. This should be included in any pre-flight request, and therefore should be included in the request URI (not the POST body).

Log in and get authentication cookies.

This action should only be used in combination with [[Special:BotPasswords]]; use for main-account login is deprecated and may fail without warning. To safely log in to the main account, use <kbd>[[Special:ApiHelp/clientlogin|action=clientlogin]]</kbd>.

Use a compact language list, with languages relevant to you.

IDs of lists to return. Use <kbd>0</kbd> for the watchlist.

Langue à utiliser pour les traductions de message. <kbd>[[Special:ApiHelp/query+siteinfo|action=query&meta=siteinfo]]</kbd> avec <kbd>siprop=languages</kbd> renvoie une liste de codes de langue, ou en spécifiant <kbd>user</kbd> pour utiliser la préférence de langue de l’utilisateur actuel, ou en spécifiant <kbd>content</kbd> pour utiliser le langage du contenu de ce wiki.

Includes language links supplied by extensions (for use with <kbd>$1prop=langlinks</kbd>).

Page property for which to enumerate pages (<kbd>[[Special:ApiHelp/query+pagepropnames|action=query&list=pagepropnames]]</kbd> returns page property names in use).

List ID; set to <kbd>0</kbd> to use the watchlist.

Attempt to remove the current user's link for the provider associated with <kbd>FooAuthenticationRequest</kbd>.

Use the form below to modify the list description or edit the list of target pages. For target pages, list one title per line and use title@domain (e.g. User_talk:Example@en.wikipedia.org) to specify a page on a different wiki.
