API:Edit

Version >1.13.3 required.

Requires $wgEnableAPI and $wgEnableWriteAPI set to true.

Token
To edit a page, an edit token is required. This token is the same for all pages, but changes at every login. If you want to protect against edit conflicts (which is wise), you also need to get the timestamp of the last revision. You can obtain these as follows:

Editing pages
Pages can be edited and created with action=edit.

Parameters

 * : Page to edit
 * : nth section to edit. Use 0 for the top section, 'new' for a new section
 * : New page (or section) content
 * : Edit token
 * : Edit comment
 * When using, this will be used for the section title
 * : If set to true, mark the edit as minor
 * : If set to true, don't mark the edit as minor, even if you have the "Mark all my edits minor by default" preference enabled
 * : If set, mark the edit as bot, even if you are using a bot account the edits will not be marked unless you set this flag
 * : Timestamp of the last revision, used to detect edit conflicts. Leave unset to ignore conflicts
 * : Timestamp when you obtained the edit token. Used to detect page deletions and recreations. Leave unset and use  to ignore conflicts
 * : If set, suppress errors about the page having been deleted in the meantime and recreate it
 * : If set, throw an error if the page already exists
 * : If set, throw a  error if the page doesn't exist
 * : Specify how the watchlist is affected by this edit, set to one of "watch", "unwatch", "preferences", "nochange":
 * : add the page to the watchlist
 * : remove the page from the watchlist
 * : use the preference settings (Default)
 * : don't change the watchlist
 * : MD5 hash (hex) of the  parameter. If this parameter is set and the hashes don't match, the edit is rejected. This can be used to guard against data corruption
 * : CAPTCHA ID from the previous request
 * : Answer to the CAPTCHA
 * : Revision ID to undo. Overrides,   and
 * : Undo all revisions from  up to but not including this one. If not set, just undo one revision

Example
Note: In this example, all parameters are passed in a GET request just for the sake of simplicity. However, action=edit requires POST requests; GET requests will cause an error. Do not forget to set the  header of your request to. The token that you received is terminated with, this needs to be urlencoded (so it will end with  ) before it is passed back.

CAPTCHAs and extension errors
If an edit requires a CAPTCHA, you'll get something like: In most cases, you won't get a math CAPTCHA, but a URL to an image (in the  field). When you've solved the CAPTCHA, retry the request (in this case with ).

Other extensions that use the APIEditBeforeSave hook may return errors using either the format described above or the usual error format.
