I'm using GCheckout.dll (Google Checkout v2.5.0.6 dll - http://code.google.com/p/google-checkout-dotnet-sample-code/downloads/list) to implement google checkout payments in a C# application.
I have configured UPS shipping on the merchant account and intentionaly not specified any shiping options in the C#, to use the ones configured in the account. For some reason though, no shipping options are apearing. Any ideas why? I though the whole point of configuring them in the merchant account is to display those when the application doesn't send any through the API
The article below may help.
There are various reasons why tax or shipping options specified in the Checkout Merchant Center are ignored. For example, if you submit a cart XML that contains the shipping-methods or tax-tables tags, the Merchant Center settings will be overriden.
