Specific parameters:
Other general parameters are available.
title

Title of the page to undelete.

This parameter is required.
reason

Reason for restoring.

Default: (empty)
tags

Change tags to apply to the entry in the deletion log.

Values (separate with | or alternative): convenient-discussions, possible vandalism, repeating characters
timestamps

Timestamps of the revisions to undelete. If both timestamps and fileids are empty, all will be undeleted.

Type: list of timestamps (allowed formats)
Separate values with | or alternative.
Maximum number of values is 50 (500 for clients that are allowed higher limits).
fileids

IDs of the file revisions to restore. If both timestamps and fileids are empty, all will be restored.

Type: list of integers
Separate values with | or alternative.
Maximum number of values is 50 (500 for clients that are allowed higher limits).
undeletetalk

Undelete all revisions of the associated talk page, if any.

Type: boolean (details)
watchlist

Unconditionally add or remove the page from the current user's watchlist, use preferences (ignored for bot users) or do not change watch.

One of the following values: nochange, preferences, unwatch, watch
Default: preferences
watchlistexpiry

Watchlist expiry timestamp. Omit this parameter entirely to leave the current expiry unchanged.

Type: expiry (details)
token

A "csrf" token retrieved from action=query&meta=tokens

This parameter is required.
Examples:
Undelete page MediaWiki.
api.php?action=undelete&title=MediaWiki&token=123ABC&reason=Restoring%20MediaWiki [open in sandbox]
Undelete two revisions of page MediaWiki.
api.php?action=undelete&title=MediaWiki&token=123ABC&timestamps=2007-07-03T22:00:45Z|2007-07-02T19:48:56Z [open in sandbox]

Beispiel

Seiten wiederherzustellen ist ein mehrstufiger Prozess:

  1. Anmelden über eine der auf API:Login beschriebenen Methoden.
  2. Ein CSRF-Token erhalten. Dieses Token ist für alle Seiten gleich, ändert sich jedoch bei jeder Anmeldung.
    api.php?action=query&format=json&meta=tokens [In der ApiSandbox ausprobieren]


  3. Sende eine POST-Abfrage mit dem CSRF-Token, um die Seite wiederherzustellen.

Der Beispielcode unten zeigt den dritten Schritt im Detail.

POST-Anfrage

Stelle zwei Versionen von Sandbox/Test wieder her.

api.php?action=undelete&format=json&title=Sandbox/Test&reason=Test%20undeleting%20via%20the%20API&timestamps=20190605072148&token=123ABC [In der ApiSandbox ausprobieren]
