XML-RPC

XML-RPC is a remote procedure call (RPC) communications protocol which uses:

• XML to encode its calls
• HTTP as a transport mechanism

Generic use

"XML-RPC" also refers generically to the use of XML for remote procedure call, independently of the specific protocol.

WordPress and XML-RPC

WordPress uses an XML-RPC interface. WordPress has its own implementation for WordPress-specific functionality in an API called the WordPress API. This should be used when possible, and your client should use the API variants beginning with the wp prefix.

With WordPress XML-RPC support, you can post to your WordPress blog using many popular Weblog Clients. The XML-RPC system can be extended by WordPress Plugins to modify its behavior.
