wp_xmlrpc_server

WordPress XMLRPC server implementation.


Description Description

Implements compatibility for Blogger API, MetaWeblog API, MovableType, and pingback. Additional WordPress API for managing comments, pages, posts, options, etc.

As of WordPress 3.5.0, XML-RPC is enabled by default. It can be disabled via the ‘xmlrpc_enabled’ filter found in wp_xmlrpc_server::login().
