I need to implement this code on the succesfull payment page and fill in the right variables. What is the best procedure to do this? The payment plugin is responsible for showing the succesfull payment page? How can I get those variables? Are they in the session?
Code:
<script src="https://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 FIELDS
"merchant_id": 108196171,
"order_id": "ORDER_ID",
"email": "CUSTOMER_EMAIL",
"delivery_country": "COUNTRY_CODE",
"estimated_delivery_date": "YYYY-MM-DD",
// OPTIONAL FIELDS
"products": [{"gtin":"GTIN1"}, {"gtin":"GTIN2"}]
});
});
}
</script>
