WooCommerce and Google Trusted Stores

Hi, I am not very experienced in the area of programming… I am getting my site active.net google verified. Google requires me to put code on all of my pages, ( I did that) and also put a unique one on the order confirmation page.I am using woocommerce…

I need to know how to
1. Access this “order confirmation page”
2. Add the code in
3. Change the code to match the details provided in the order

The google code template is this:
<!– START Google Trusted Stores Order –>
<div id=”gts-order” style=”display:none;” translate=”no”>

<!– start order and merchant information –>
<span id=”gts-o-id”>MERCHANT_ORDER_ID</span>
<span id=”gts-o-domain”>MERCHANT_ORDER_DOMAIN</span>
<span id=”gts-o-email”>CUSTOMER_EMAIL</span>
<span id=”gts-o-country”>CUSTOMER_COUNTRY</span>
<span id=”gts-o-currency”>CURRENCY</span>
<span id=”gts-o-total”>ORDER_TOTAL</span>
<span id=”gts-o-discounts”>ORDER_DISCOUNTS</span>
<span id=”gts-o-shipping-total”>ORDER_SHIPPING</span>
<span id=”gts-o-tax-total”>ORDER_TAX</span>
<span id=”gts-o-est-ship-date”>ORDER_EST_SHIP_DATE</span>
<span id=”gts-o-est-delivery-date”>ORDER_EST_DELIVERY_DATE</span>
<span id=”gts-o-has-preorder”>HAS_BACKORDER_PREORDER</span>
<span id=”gts-o-has-digital”>HAS_DIGITAL_GOODS</span>
<!– end order and merchant information –>

<!– start repeated item specific information –>
<!– item example: this area repeated for each item in the order –>
<span class=”gts-item”>
<span class=”gts-i-name”>ITEM_NAME</span>
<span class=”gts-i-price”>ITEM_PRICE</span>
<span class=”gts-i-quantity”>ITEM_QUANTITY</span>
<span class=”gts-i-prodsearch-id”>ITEM_GOOGLE_SHOPPING_ID</span>
<span class=”gts-i-prodsearch-store-id”>ITEM_GOOGLE_SHOPPING_ACCOUNT_ID</span>
<span class=”gts-i-prodsearch-country”>ITEM_GOOGLE_SHOPPING_COUNTRY</span>
<span class=”gts-i-prodsearch-language”>ITEM_GOOGLE_SHOPPING_LANGUAGE</span>
</span>
<!– end item 1 example –>
<!– end repeated item specific information –>

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