After quite a bit of struggling, I've finally got Google Checkout's notification API working (a bit) and I think I understand it.

However my log file, is showing that today I've been getting order- state-change-notifications for archived orders which over 2 weeks old. Now this is fine - it doesn't affect my system as these notifications aren't sending nay new information but I can't imagine it's correct that i should be getting callbacks on such old orders which have not changed.

An example (from googlemessage.log)

========= Wed May 28 13:36:17 BST 2008:- <?xml version="1.0" encoding="UTF-8"?> <order-state-change-notification xmlns="http://checkout.google.com/ schema/2" serial-number="734915112697802-00008-1"> <timestamp>2008-05-02T10:13:19.106Z</timestamp> <google-order-number>734915112697802</google-order-number> <new-fulfillment-order-state>PROCESSING</new-fulfillment-order- state> <new-financial-order-state>CHARGING</new-financial-order-state> <previous-fulfillment-order-state>PROCESSING</previous-fulfillment- order-state> <previous-financial-order-state>CHARGEABLE</previous-financial-order- state> </order-state-change-notification> ============

This order is in my archive with the following dates:

Sold on 2 May 2008 11:13:16 GMT+01:00 Charged on 2 May 2008 11:13:19 GMT+01:00 Confirmed on 2 May 2008 11:13:19 GMT+01:00

Also...

I also seem to be getting numerous identical new-order-notifications for the same orders coming through every 30-60 seconds but failing to get the relevant order-state-change-notifications to say the order is chargeable/charging/charged/etc. I got 5 identical new-order- notifications for an order (id: 759290672594522) today in 2 minutes (12:12 - 12:14pm)

Any ideas?
