App on Android market - HTTP notifications don't come

Question

I have a paid app on Android Market. I've set up an HTTPS notification URL in Google Checkout settings. Yet notifications don't come.

My Google Checkout settings under Integration go like this:

• My company will only post digitally signed carts - checked
• API callback URL - provided, it's HTTPS and it's valid
• Notification as XML - checked
• API version - 2.5
• Notification filtering - checked

Please, what am I doing wrong? Are realtime order notifications supported for Android Market at all? If so, is there a separate UI for setting those up?

EDIT: any data points would be welcome. If you sell stuff on the Market and do get those HTTP notifications, let's compare the setups.

EDIT2: seriously considering timed polling of my Google Checkout account. :(

EDIT3: contacted Google Checkout support. No substantial response for over a week. :(( On the brighter side, it is possible to retrieve the list of one's Google Checkout orders, with date and state filtering. On to retrieving order details...

Answer 1

The support rep told me it's by design, implement account polling with notification history API.

Specifically: http://code.google.com/apis/checkout/developer/Google_Checkout_XML_API_Order_Report_API.html describes how to get the list of orders in given state

http://code.google.com/apis/checkout/developer/Google_Checkout_XML_API_Notification_History_API.html lets you retrieve order details (getting just the "new order" notification is sufficient in my case).

EDIT: you cannot use some parts of the Google Checkout API with Android Market orders (like marking as archived). This is not documented.
