title: WooCommerce API - Update Order Meta Fields
body: <p>Does the WooCommerce <a href="http://woothemes.github.io/woocommerce-rest-api-docs" rel="noreferrer">Rest API</a> offer any way to update meta fields?</p>
  
  <p>They have an Extension which adds the ability to add tracking numbers to an order when it's shipped using meta fields, but don't have any documentation on how or if it's possible to update the order's meta fields with this information via their REST API.</p>
