I've seen this a couple of times when using a currency for payment different than the one configured on the merchant account. Google Checkout has a log section when you're logged in, which contains more info about the error.

Thanks Soren, exactly that was the issue...

Thanks for updating the thread with your findings.

We are seeing this issue as well.  We are running umbraco 4.9.1 with uCommerce 3. 

I didn't see a place to specify currency in our Google Checkout sandbox, but we are based in the US so I assume it is USD.  I have cleared out the countries and currencies from our uCommerce setup so that only 'USD' is left.  This should mean that the currencies are consistent, but we still get the 'Bad Request' error.

I looked in the Google Checkout sandbox for the logs to try and debug what was posted, but when i got to tools->integration console there is nothing in the list. 

Is there another place to look for the logs? 

I have the GoogleCheckout.config updated with our sandbox merchant ID and Key, but i'm not sure how to verify what is being sent by uCommerce, and to who.

You're right that it's probably a currency mismatch scenario.

Trying clearing your cookies to force uCommerce to create a new cart for you with USD currency and retry.

Thanks for the reply.  Unfortunately, no luck with clearing the cookies.

With Firefox, I tried clearing all cookies that were displayed in Firebug.  I still received the 'Bad Request' error.  I then tried bringing up the site and going through checkout in Chrome, which i had never used for the site before (so there should be no lingering cookies).  I also received the 'Bad Request' error.

When i tried the checkout in IE (also first time for the website), i received a different error immediately on post:

HTTP 500: A potentially dangerous Request.Form value was detected from the client (send-order="...ete Order <I class="icon-arrow...").

I still see no indication in the Google Checkout integration console of any request, so it doesnt' look like it is ever getting to my account.

Is there a way to trace what 'UCommerce.Transactions.Payments.GoogleCheckout.GoogleCheckoutPaymentMethodService' is sending, and to where?  Is there a way to figure out what about the request is a 'Bad Request'?

I tried using Fiddler to inspect what was being sent, but i believe that only tracks from my browser up to my web server, not from the web server to Google.  One possibly interesting thing i noticed is that in IE, the raw 'send' data was: "send-order=Complete+Order+%3CI+class%3D%22icon-arrow-right+icon-white%22%3E%3C%2FI%3E", while in Chrome it was simply: "send-order="

There isn't a whole lot of configuration on the uCommerce side for Google checkout, just a few entries in the GoogleCheckout.config file and the payment method item, and those looked fine. 

Are there configuration setups in the Google Sandbox that could have been missed?

Are there web server settings that need to be specified for the communication to Google to work?

Solved!

It turns out that after all that technical debugging, it was actually just a matter of the GoogleCheckout.config file having 'testMode=false' while i was still in the Google sandbox. 

Hi Erik,

Thanks for beint awesome and posting the follow-up in the forum.

I will update the docs for Google Checkout with a note about the config requirement for sandbox.

is working on a reply...
