My client's Google Checkout account is based in UK, hence its default currency is GBP. Accordingly, I thought I'd let users pay using GBP - they actually think they are paying in USD but behind the scenes I convert USD to GBP according to the conversion rate.
Anyway, I keep getting the following error message:
The currency used in the cart must match the currency of the seller account. You supplied a cart with USD and the seller account is associated with GBP.
When I check the Integration Console for the message that is being sent from the website to Google Checkout's API, this is what I get:
_type=checkout-shopping-cart&shopping-cart.items.item-1.item-name=Credits&shopping-cart.items.item-1.item-description=Description&shopping-cart.items.item-1.item-currency=GBP&shopping-cart.items.item-1.unit-price=64.42&shopping-cart.items.item-1.quantity=1
As you can see, I made sure the currency is set to GBP, yet it still complains. Is there anything I can do to fix this?
