API:Options

Token
To change options, an options token is required.

Options tokens can be obtained via action=query&meta=tokens

In older versions, a token can be obtained via action=tokens&type=options:

Changing options
Options can be changed using action=options.

While this API is primarily intended for changing options which are registered by MediaWiki core or extensions and available on Special:Preferences, since you can also use it to set arbitrary user options that can be used by user-scripts or external editors.

userjs options must begin with the prefix.

The following limits apply to all user options:
 * The length of the key must not be more than 255 bytes
 * The key must consist only of ASCII letters, numbers, hyphens and underscores (a-z, A-Z, 0-9, _, -)
 * The byte length (not character length) of the value must be <= 65535. However, please minimize the length used (both per-option and total), because user options are downloaded in their entirety for every page view. Only very small datums should be stored.

There are currently no limit on the number of user options you can set at once. You can store a tree of data within a user option by encoding it as a JSON string.

Parameters

 * Note: Providing only names of options without equal sign (e.g. ) results in resetting them. In the case of an arbitrary   name/value pair, the resetting results in the removal of the name/value pair; in other words - deletion.

The change parameter cannot be used to set a value which contains a pipe character "|", as it is used by the API to separate options. If you need to set such a value (for example, a user signature) use an optionname & optionvalue pair.

Available Options
The following is an example list obtained with /w/api.php?action=query&format=json&meta=userinfo&uiprop=options for a Wikipedia account.

Note that most of the options listed here are defined by various MediaWiki extensions, like Echo, VisualEditor, WikiLove, Gadgets or EducationProgram, among others.

Example
Note: In this example, all parameters are passed in a GET request for the sake of simplicity. However, action=options requires POST requests; GET requests will cause an error.
