Magento Category Listing for WordPress allows you to use a simple shortcode to display a responsive, paginated category listing of Magento products within your WordPress content.
The plugin comes with an easy-to-use shortcode generator, and allows you to modify a number of parameters, including columns, products-per-page, button colours, and much more; perfect for integrating seamlessly into your theme.
Your Magento and WordPress websites should reside on the same server, but do not need to utilise the same domain name.
