Has anyone implemented transactional messages in Marketo using any of the available APIs?

@Tim - we are also in that same process. Responding here to get updates on this thread. Thanks to all who have shared so far.

I believe Magento developers would be able to help you with such an integration, or really any Marketo agency with a strong programming team.

@Amy, I'll continue to post either in this thread or alert you to another on how the project is going. We're taking this project internally though with our own developer team.
