google checkout is sending my other transaction to eshop

[meereck]

Hello guys,
I have configured google checkout in prestashop, using it in https mode.
I also use my google checkout account for other transaction and billings.

The problem is that google checkout is trying to send an order to my eshop even if the order didnt come from the eshop, but was issued manually via google checkout.

Does anybody know how to configure google checkout so that it sends orders from eshop back to the eshop only?

Hope the explanation is clear to you,
thank you in advance,
Meereck
