title

Title of the page to roll back. Cannot be used together with pageid.

pageid

Page ID of the page to roll back. Cannot be used together with title.

Type: integer
tags

Tags to apply to the rollback.

Values (separate with | or alternative): possible vandalism, repeating characters
user

Name of the user whose edits are to be rolled back.

This parameter is required.

Default: (empty)
markbot

Type: boolean (details)
watchlist

Unconditionally add or remove the page from the current user's watchlist, use preferences or do not change watch.

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

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

For compatibility, the token used in the web UI is also accepted.

This parameter is required.
Examples:
Roll back the last edits to page Main Page by user Example.
api.php?action=rollback&title=Main%20Page&user=Example&token=123ABC [open in sandbox]
Roll back the last edits to page Main Page by IP user 192.0.2.5 with summary Reverting vandalism, and mark those edits and the revert as bot edits.
api.php?action=rollback&title=Main%20Page&user=192.0.2.5&token=123ABC&summary=Reverting%20vandalism&markbot=1 [open in sandbox]

Making any POST request is a multi-step process:

  1. Log in, via one of the methods described in API:ログイン .
  2. CSRF トークン を取得します:
  3. Send a POST request, with the CSRF token, to take action on a page and in this process gain editpage rights to the given page:
  4. GET a rollback token:

POST リクエスト

Send a POST request, with a rollback token to revert a user's edits to the Sandbox page.

以下の例では、わかりやすさのためだけに、パラメーターをGETで渡すような形で書いてあります。実際には、action=rollback のリクエストはPOSTで投げる必要があります(GETだとエラーになります)。

レスポンス

The Response section below is for the final POST request, to revert the edits to the Sandbox page.

{
    "rollback": {
        "title": "Sandbox",
        "pageid": 94542,
        "summary": "Reverted edits by [[Special:Contributions/41.190.3.231|41.190.3.231]] ([[User talk:41.190.3.231|talk]]) to last revision by [[User:Didicodes|Didicodes]]",
        "revid": 381084,
        "old_revid": 381083,
        "last_revid": 381070
    }
}

The revision IDs in the response are:

  • revid - The ID of the new revision created by the rollback.
  • old_revid - The ID of the newest revision being rolled back. Before the rollback, this was the current revision.
  • last_revid - The ID of the revision being restored by the rollback. This is the newest revision having been rolled back.

権限

Rollback requires both the editpage and the rollback right on the target page; currently, this means that OAuth consumers, bot passwords etc. require both the editpage and the rollback grant – rollback alone is not enough!

起こりうるエラー

In addition to the usual stuff:

コード 情報
alreadyrolled ロールバックしようとしたページは既にロールバックされています
missingparams One of the parameters "title" and "pageid" is required.
mustpostparams The rollback module requires a POST request.
notitle パラメーター title を設定してください。
notoken パラメーター token を設定してください。
nouser パラメーター user を設定してください。
onlyauthor The page you tried to rollback only has one author
permissiondenied The action you have requested is limited to users in one of the groups: Administrators, Rollbackers

パラメーターの履歴

  • v1.24: pageid を導入しました
  • v1.27: tags を導入しました
  • v1.17: watchlist を導入しました

追加的な注記

  • 必要があれば、ロールバックの操作とロールバックされた編集の両方をBot編集だとマークして、デフォルトのSpecial:RecentChangesから隠すことができます。
