Windows Phone in-app purchases: Receipt validation certificate missing

We are getting HTTP 404 when trying to download the certificate for validating the receipt. I've seen two different URIs to fetch the certificate, of which the other is a redirect to the first one. Below is the supposed URI to the certificate:

Certificate with id: A656B9B1B3AA509EEA30222E6D5E7DBDA9822DCD

The address should be fine as I'm able to download another certificate with a different id mentioned here (id: b809e47cd0110a4db043b3f73e83acd917fe1336)

My guess is, that this is due to our app being a beta app at the moment and since I can find the same certificate id from the example receipt in this sample here, but haven't been able to verify it.

Edit: the in-app products are also free at the moment if that matters

This was a bug, as the Beta certificate was never deployed to the server. I have worked to get that added and now you should be able to use the sample code, as is, and download the certificate without receiving a 404.

Ok, I finally got this to work.

The link you posted with the b809.. id is for windows apps, not windows phone 8 apps. It appears the certificate is different.

The id from the test receipt you posted is the same I am getting in my beta app and I think it will be the same when we go out of beta.

Inside the example found here, in the zip file there is a file called IapReceiptProduction.cer. If you double click it and view details you will see it has a thumbprint that matches your certificate id.

I included that file in my solution and I load it using the sample code from my link and that works.

I just hope they wont change the certificate at some point.

EDIT: It appears the phone emulator does not get signed receipts (my working test was on an actual phone). The receipts I get in the emulator also have a different certificate id (FB3D3A6455095D2C4A841AA8B8E20661B10A6112).
