We know you’ve been waiting for a full-fledged WooCommerce API, and while that particular piece of greatness is still a few months away (see this Github issue for details), we’ve developed a simple XML-RPC API to help you start integrating WooCommerce with your backend systems today. This has been tested over the past few months with a handful of clients and we’re ready to release it to the world.
Currently it only supports updating order status and order tracking (most helpful when used with the WooCommerce Shipment Tracking extension), but we’re planning more API calls. To get started, just download and install the plugin and add a user with at least the “Editor” role. Follow the steps for testing on the comprehensive readme. We’ll be adding to the WordPress.org plugins repository in the future.
