I just got this error but it appears the transaction did not complete so there is no order number associated with it.We timed out waiting for your server at https://www.e-junkie.com/gc/ResponseHandler.php -- the error we got is: Read timed out Your server must respond faster to merchant calculation callback requests.
Google provides a server 3 seconds to respond. Some times it can take longer. However, we pass the backup data along with the order so this is not an issue.
