XML-RPC (Remote Procedure Call)
Definition
XML-RPC is a communication protocol that uses XML to encode remote procedure calls and HTTP as the transport mechanism.
In WordPress and WooCommerce, it allows external applications to interact with your website programmatically.
This can include publishing content, editing products, or retrieving order information.
Good or Bad?
Good?
Useful for enabling third-party integrations, mobile apps, and remote publishing.
Bad?
Known for security vulnerabilities if left enabled unnecessarily.
Why does it matter?
- Allows automation of certain store management tasks
- Enables mobile apps or external systems to interact with WooCommerce
- Useful for integrations like desktop blogging tools or custom CRM systems
- Needs careful management due to frequent exploitation in brute-force attacks
Common Mistakes
- Leaving XML-RPC enabled when not in use
- Not limiting access or monitoring activity
- Failing to secure it with proper authentication
- Assuming it’s the same as REST API
How to Improve It?
- Disable XML-RPC if your store doesn’t use it
- Use a plugin or server-level configuration to restrict access
- Monitor your server logs for suspicious XML-RPC activity
- Switch to REST API for more secure and modern integrations
Recommended Plugin
Disable XML-RPC-API
Lightweight plugin that disables XML-RPC completely to prevent abuse and potential security risks.
Real-World Example
A WooCommerce store noticed repeated login attempts through XML-RPC.
After disabling the feature and switching to REST API for integrations, login-related attacks dropped by 90% and server performance improved.

FAQs
Is XML-RPC still needed for WooCommerce?
Not usually. REST API is more secure and widely used today.
How can I check if XML-RPC is enabled on my store?
Try visiting yourstore.com/xmlrpc.php. If it returns a response, it’s active.
Can I disable XML-RPC safely?
Yes, if no integrations rely on it. Be sure to confirm before disabling.
