By understanding how to securely manage and utilize the xmlrpc.php API, you can take full advantage of its capabilities while protecting your website.

Access the WordPress xmlrpc.php API

By default, your hosting service has the WordPress xmlrpc.php API activated. Accessing the WordPress xmlrpc.php API is straightforward. By default, it is enabled on your WordPress installation.

To use it, you’ll need the URL of your WordPress site followed by /xmlrpc.php

For example, if your website is infoceptor.com, the API endpoint would be infoceptor.com/xmlrpc.php

To interact with the API, you’ll need a program that supports XML-RPC, such as a third-party app or a custom script. Always make sure your credentials (username and password) are securely stored.

Disable the WordPress xmlrpc.php API

Disabling the xmlrpc.php API can enhance the security of your WordPress site if you don’t need remote access features.

Here are a few methods to disable it:

  1. Use a Plugin:
  • One of the simplest ways to disable xmlrpc.php is by using a plugin. Plugins like Disable XML-RPC can easily turn off the API. Simply install and activate the plugin from the WordPress plugin repository.

2. Adding Code to Functions.php:

  • You can also disable xmlrpc.php by adding a few lines of code to your theme’s functions.php file. Here is the code snippet to do this:
add_filter('xmlrpc_enabled', '__return_false');
  • This filter disables the XML-RPC API for your WordPress site.

🚨 Always use caution when accessing and editing code in your functions.php file.

3. Using .htaccess:

  • Another method is to block access to the xmlrpc.php file using your .htaccess file. Add the following lines to your .htaccess file:
<Files xmlrpc.php>
    Order Deny,Allow
    Deny from all
</Files>
  • This will deny all requests to the xmlrpc.php file, effectively disabling the API.
