    // On Order received endpoint only
    if( is_wc_endpoint_url( 'order-received' ) ) :

    $order_id = absint( get_query_var('order-received') ); // Get order ID

    if( get_post_type( $order_id ) !== 'shop_order' ) return; // Exit

    $order = wc_get_order( $order_id ); // Get the WC_Order Object instance
    ?>
    <script>
      gtag('event', 'conversion', {
          'send_to': 'AW-746876528/x5W1CLfA8JoBEPDckeQC',
          'value': <?php echo $order->get_total(); ?>,
          'currency': '<?php echo $order->get_currency(); ?>',
          'transaction_id': '<?php echo $order_id; ?>'
      });
