I am using google checkout with a ruby on rails application. I have added merchant private data in HTML API like this:
<input type="hidden" name="shopping-cart.merchant-private-data" value="123">
Merchant private data is only accessible in new order notification.
Is there any way to access it in order state change notification??
Not that I know of (only in new-order-notification
).
You'd probably want to know that Google Checkout will be retired in November.
