API:Rollback/da
| This page is part of the MediaWiki Action API documentation. |
| MediaWiki-version: | ≥ 1.12 |
POST request to revert the last series of edits made by one user to a given page.
This functionality is identical to the one provided by the rollback links in the graphical interface on history page.
API-dokumentation
Eksempel
Making any POST request is a multi-step process:
- Log in, via one of the methods described in API:Login.
- GET a CSRF token:
- Send a POST request, with the CSRF token, to take action on a page and in this process gain
editpagerights to the given page: - GET a rollback token:
- If your wiki is using MediaWiki 1.24+, follow these instructions:
- Rollback tokens aren't universal: they are not only different for every login, but also depend on the title of the page and the name of the user whose edits are to be rolled back. For MediaWiki 1.23 or earlier, follow these instructions:
POST request
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.

"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

Tilladelser
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!

Additional notes
- Optionally, both the rollback and the edits being rolled back can be marked as bot, which hides them from Special:RecentChanges by default.
