Error pages are served up via .HTACCESS, if you are using Apache you would use the ErrorDocument directive and add the status and URL to it.

Woo have now provided a CRUD interface so use that instead. $post_id = wp_insert_post( array( ‘post_title’ => $title, ‘post_type’ => ‘product’, ‘post_status’ => ‘publish’, ‘post_content’ => $body, )); … Read more
So if you want to send the reset password link and you have access to the code base, you can use the following snippet and you can modify it further.
