Additional notes
- For older versions of MediaWiki, you can use API:Tokens (action) or API:Info to get an edit token in place of login token.
- While executing the code snippets provided on this page, remember to use
https://test.wikipedia.org/w/api.phpas the endpoint, so that you don't accidentally delete pages on production wikis. - In addition to the
deleteright, other rights may be required, depending on the location and type of page.
Deleting a user's .css page, for example, also requires the editusercss right.
