WooCommerce Endpoints content

Dang it…must be blind….FOUND IT. The solution is, that since this is a custom hook, and most likely using JQuery, you place the end point action within the call.

Instead of this:

  function mylistings_information_endpoint_content() 
    {
     echo 'THIS IS A TEST OF THE CONTENT';
    }
   add_action( 'woocommerce_account_information_endpoint', 'mylistings_information_endpoint_content' );

It is this:

  function **mylistings**_information_endpoint_content() 
    {
     echo 'THIS IS A TEST OF THE CONTENT';
    }
   add_action( 'woocommerce_account_**mylistings**_endpoint', 'mylistings_information_endpoint_content' );
