Archives For XML API

There is a lot going on when Magento actually sends a cart to Google Checkout, even more so if you are using Merchant calculated shipping. As a result lots of things can go wrong, with the merchant calculated shipping callback or with the actual server to server posting of the cart contents.

To help you with diagnosing problems I thought I’d shared my top 3 methods for finding out what is going wrong when Magento and Google Checkout are not communicating properly.

If the Google callbacks have failed or incorrect XML has been sent to Google you will find a report of the errors here. It is a good idea to keep an eye on the timestamps as you do not want to wind up chasing an old problem. It’s also good to periodically check this console while in production, just in case something starts to go wrong.

able to find it: result: address-id: XXXXXX"

The problem was that the XML response Magento was sending back had the correct calculations for each shipping method that was available but it didn’t include the shipping methods that were not available for the address. These are required according to the Google Checkout XML API Docs.
