How to …. get to the Woocommerce Thank You page

Hey Adendum!

Try adding this code to theme / child theme functions.php:

add_action( 'woocommerce_thankyou', function( $order_id ){
    $order = new WC_Order( $order_id );

    $url = 'http://redirect-here.com';

    if ( $order->status != 'failed' ) { 
        echo "<script type="text/javascript">window.location = '".$url."'</script>";
    }
});
