token

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

This parameter is required.
Examples:
Change the language of the page MediaWiki to Basque.
api.php?action=setpagelanguage&title=MediaWiki&lang=eu&token=123ABC [open in sandbox]
Change the language of the page with ID 123 to the wiki's default content language.
api.php?action=setpagelanguage&pageid=123&lang=default&token=123ABC [open in sandbox]


Example

Making any POST request is a multi-step process:

  1. Log in, via one of the methods described on API:Login .
  2. GET a CSRF token .
  3. Send a POST request, with the CSRF token, to take action on a page.

The sample code below covers the final step in detail.
