One important file on your WordPress.com blog is called xmlrpc.php.
Where is it found?
It is found at yoursite.wordpress.com/xmlrpc.php. Replace mysite.wordpress.com with your site’s URL.
XML-RPC server accepts POST requests only.
This is not an error. It is a statement saying that only POST requests can be sent. Sent? We will talk about this in a second.
The WordPress.com app for iOS and Android uses the xmlrpc.php file. In fact, this is crucial for the application to work.
A ‘request’ is what the program sends to the xmlrpc.php file. A POST request, mentioned earlier, is a request to post a WordPress blog post or page onto your blog.
You can use several xmlrpc coding libraries to post to your blog with code. As there are so many, I can’t give you documention for all of them.
I hope you now know about the usage of xmlrpc.php. If you have any questions or concerns, leave them below in the comments section.
