Hello,

We are trying to implement the Google Customer Review survey opt-in module by adding the following code to the view checkout / end.php


<!-- BEGIN GCR Opt-in Module Code -->
<script src=" apis.google.com/js/platform.js?onload=renderOptIn "
async defer>
</script>

<script>
window.renderOptIn = function() {
window.gapi.load('surveyoptin', function() {
window.gapi.surveyoptin.render(
{
// REQUIRED
"merchant_id": "100618039",
"order_id": "ORDER_ID",
"email": "CUSTOMER_EMAIL",
"delivery_country": "COUNTRY_CODE",
"estimated_delivery_date": "YYYY-MM-DD"

// OPTIONAL
"products":[{"gtin":"GTIN1"}, {"gtin":"GTIN2">}],
"opt_in_style": "CENTER_DIALOG"
});
});
}
</script>
<!-- END GCR Opt-in Module Code -->

<!-- BEGIN GCR Language Code -->
<script>
window.___gcfg = {
lang: 'en-US'
};
</script>
<!-- END GCR Language Code -->


We are having a bit of trouble determining the correct values to use for the variables marked in bold. This code was pulled directly from Google's Integration guide so everything else should be correct aside from the bold values that we need to replace. Here is the data that Google needs from these variables:

ORDER_ID: A unique ID for the order (order number).
CUSTOMER_EMAIL: The customer's email address, in the format This email address is being protected from spambots. You need JavaScript enabled to view it..
COUNTRY_CODE: The two-letter country code identifies where the customer's order will be delivered. This value must be in ISO 3166-1 alpha-2 format. Do not use “ZZ” for this field. For example, "US".
YYYY-MM-DD: The estimated delivery date for the order, where YYYY is the year, MM is the month, and DD is the day. For example, "2016-09-13". (We may be able to use the order creation date for this field, if an estimated delivery date for orders is unavailable.)

Can you offer a bit of help as to how we should enter these variables to send the correct data to Google?

Hi Nicolas,

Thanks for looking into this. We've been trying to implement the code in our view: checkout/end.php but Chrome DevTools is generating the error: "delivery_country cannot be empty!" when we run through checkout.

Could there be an issue with the variable for the country code, or any ideas what else could be causing this?

Here is the code snippet we are adding to the beginning of the checkout/end.php file.

Nicolas,

This line seems to have done the trick:

<?php echo $this->order->shipping_address->address_country_code_2; ?>
