token

Example[edit]

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 .

    The sample query above is for wikis running MediaWiki 1.24+.

    For wikis running earlier versions of MediaWiki, tokens for this operation can be obtained via action=tokens with type=watch (MediaWiki 1.20+), or by using the following query:

  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.

POST request[edit]

Add an article to your watchlist

Response[edit]

{
    "batchcomplete": "",
    "watch": [
        {
            "title": "Stone Forest",
            "watched": ""

Additional notes[edit]

  • When running the sample code via a bot, make sure that the bot has the Edit your watchlist option set to true, by visiting the Special:BotPasswords page.
  • This module uses CSRF tokens, not watchlist tokens. CSRF tokens are generally used for POST requests and wiki-modifying actions throughout the Action API , whereas watchlist tokens are used specifically to view another user's watchlist.
  • Unlike API:Watchlist , which allows you to read an account's private watchlist without logging in, this module requires you to log directly into the account you want to alter.
