Google Checkout - XML Shipping Data Not Showing Up in Back Office

[Yun]

Thanks to this brilliant thread:

[solved] Allow Google Checkout to calculate shipping by carrier.

I now have Google Checkout calculating both shipping and tax for my store and everything is working perfectly, except for one thing. The calculated shipping value is not being returned to the Prestashop back office.

The order shows up correctly, but the shipping is $0, which is the value I have applied for my default carrier because I don’t want Prestashop to calculate the order for me. The carrier seems to be required for the checkout process to work (no carrier gets the ‘There is no carrier….etc.’ error and stops the process).

I know it is this value showing up because, if I change the carrier default to $10, this is the value that shows up in the back office orders irrespective of what shipping has been calculated by Google.

I have checked the xml notification being returned by Google (in googlemessage.log) and it includes the correct calculated shipping cost (e.g. 10.052).

So – it seems to me that there must be a way to pull this data into the back office instead of the default shipping fee. I just can’t find out where or how to do it.

This is my last big obstacle to having the store fully functional and I’ve spend most of today & yesterday trying to work it out. Can anyone help?

Thanks in advance,
Yun
