Google Trusted Stores with WooCommerce

This is how I’ve done it. Works for me.

Trusted Stores Badge Code
a) create child theme
b) create functions.php under your child theme with this code

<?php
add_action('wp_footer', 'add_gts_badge_code');

function add_gts_badge_code() { ?>
// Paste your Trusted Stores Badge Code here
<?php } ?>

Order Confirmation Module Code
a) create override woocommerce/checkout/thankyou.php file under your child theme
b) add this code after <div class="clear"></div>

<!-- START Google Trusted Stores Order -->
<div id="gts-order" style="display:none;" translate="no">

  <!-- start order and merchant information -->
  <span id="gts-o-id"><?php echo $order->get_order_number(); ?></span>
  <span id="gts-o-email"><?php echo $order->billing_email; ?></span>
  <span id="gts-o-country"><?php echo $order->billing_country; ?></span>
  <span id="gts-o-currency"><?php echo $order->order_currency; ?></span>
  <span id="gts-o-total"><?php echo $order->order_total; ?></span>
  <span id="gts-o-discounts"><?php echo $order->cart_discount; ?></span>
  <span id="gts-o-shipping-total"><?php echo $order->order_shipping; ?></span>
  <span id="gts-o-tax-total"><?php echo $order->order_tax; ?></span>
  <span id="gts-o-est-ship-date"><?php echo date('Y-m-d', strtotime('+1 weekday')); ?></span>
  <span id="gts-o-est-delivery-date"><?php echo date('Y-m-d', strtotime('+6 weekday')); ?></span>
  <span id="gts-o-has-preorder">N</span>
  <span id="gts-o-has-digital">N</span>
  <!-- end order and merchant information -->

  <!-- start repeated item specific information -->
  <span class="gts-item">

  <?php
	$gts_cart_items = $order->get_items();
	foreach ( $gts_cart_items as $gts_line_item ) {
		print ("\t<span class='gts-i-name'>$gts_line_item[name]</span>\n");
		print ("\t<span class='gts-i-price'>$gts_line_item[line_total]</span>\n");
		print ("\t<span class='gts-i-quantity'>$gts_line_item[qty]</span>\n");
		print ("\t<span class='gts-i-prodsearch-id'>YOUR_ITEM_GOOGLE_SHOPPING_ID</span>\n");
		print ("\t<span class='gts-i-prodsearch-store-id'>YOUR_ITEM_GOOGLE_SHOPPING_ACCOUNT_ID</span>\n");
	}
  ?>

  </span>
  <!-- end repeated item specific information -->

</div>
<!-- END Google Trusted Stores Order -->

ps. I’ve seen a neater example on the web on how to handle digital downloads and backorder items, however in my case they don’t apply so I’ve used static values.

Good luck.
