Values (separate with | or alternative): AWB, convenient-discussions
user

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

This parameter is required.
Type: user, by any of username, IP, Temporary user, interwiki name (e.g. "prefix>ExampleName") and user ID (e.g. "#12345")

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.

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

This parameter is required.
Examples:
Roll back the last edits to page MediaWiki by user Example.
api.php?action=rollback&title=MediaWiki&user=Example&token=123ABC [open in sandbox]
Roll back the last edits to page MediaWiki 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=MediaWiki&user=192.0.2.5&token=123ABC&summary=Reverting%20vandalism&markbot=1 [open in sandbox]


Beispiel

Making any POST request is a multi-step process:

  1. Log in, via one of the methods described in API:Login .
  2. GET a CSRF token :
    api.php?action=query&format=json&meta=tokens [try in ApiSandbox]
  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:
    api.php?action=edit&format=json&title=Sandbox&appendtext=Hello&token=sampleCsrfToken123+\ [try in ApiSandbox]
  4. GET a rollback token:

POST-Anfrage

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

In this example, all parameters are passed in a GET request just for the sake of simplicity. However, action=rollback requires POST requests; GET requests will cause an error.
api.php?action=rollback&format=json&title=Sandbox&user=41.190.3.231&token=d36a517a732991d5aaafae8bd40eee4a5c7bf75a+\\ [try in ApiSandbox]

Antwort

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.

Task T212851

Rollback requires both the edit 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!
