POST request to revert a file to an old version.


To revert a file to an older version, a CSRF token is required. The CSRF token is the same for all pages, but changes at every login. CSRF tokens can be obtained via action=query&meta=tokens with type=csrf (MW 1.24+). For older versions, you can use API:Tokens (action) or API:Info to get an edit token.


  • filename: Target filename, without the File: prefix.
  • archivename: Archive name of the revision to revert to. This should include the timestamp of the revision and the name of the file in the format: yyyyMMddhhmmss!filename. This information can be found using Imageinfo with iilimit set higher than 1. When looking at a file's page, the seconds will not be displayed; the needed archive name can be found by hovering over the older image and looking at the displayed file name. (Note that the ! will already have been urlencoded as %21.)
  • token: A CSRF token obtained as per the Tokens section, above. Take care to urlencode the trailing +\ as %2B%5C
  • comment: Upload comment.
