Token

To block or unblock a user, a token is required. This token is equal to the edit token and the same for all blocks, but changes at every login. For MediaWiki 1.24 onwards, the needed token can be obtained via meta=tokens with the type set to csrf. For MediaWiki 1.20–1.23, see API:Tokens (action); for older versions, see API:Info or use the now-removed gettoken parameter.

Obtaining a block/unblock token

Blocking users

Users can be blocked with action=block. This must be sent as a POST request. As such, don't forget to append an = to parameters with no value (e.g., autoblock=, not just autoblock).

Parameters

  • user: The username, IP address or IP range you want to block.
  • token: A previously obtained block token. Take care to properly urlencode the + and \.
  • expiry: Expiry timestamp. Relative expiry times, like 5 months or 2 weeks are also accepted. If set to infinite, never, or not set at all, the block will never expire. (Default: never)
  • reason: The reason for the block (optional).
  • anononly: If set, only anonymous logins from the user's IP will be blocked, thus forcing the user to log in or create an account in order to be able to edit.
  • nocreate: If set, block account creation from the user's IP.
  • autoblock: If set, automatically block the IP address last used by this user, and any subsequent IPs they try to login from.
  • noemail: If set, prevent the user from sending email through Special:Emailuser. (Requires the "blockemail" right.)
  • hidename: Hide the username from the block log. (Requires the "hideuser" right.)
  • allowusertalk: Allow the user to edit their own talk page (depends on $wgBlockAllowsUTEdit) 1.14+
  • reblock: If the user is already blocked, overwrite the existing block 1.14+
  • watchuser: Watch the user/IP's user and talk pages 1.18+
  • gettoken: If set, a block token will be returned, and no other action will be taken (Deprecated in 1.20) (Removed in 1.21)
  • tags: Tags to apply to the entry in the block log. 1.29+

Example

Note: In this example, all parameters are passed in a GET request just for the sake of simplicity. However, action=block requires POST requests; GET requests will cause an error. Blocking Example for 1 day, disabling account creation and email
