I would ask about the proper design and approach for Transactional Api Journeys with localized content. Imagine status Emails for 6 different countries. Right now it is done using a multistep Journey with an API Entry Event. Inside Journey, there is a decision split for colour or language. So the right person receives a correct status email. The downside of that solution is a slightly low delivery time and no option to set the callback with track data.
A much better solution in my mind is to use API Transactional Journeys, but each separate Journey for each case sounds painful to me.
Is there a way to create decision splits in Transactional Api Journeys in Marketing Cloud or just AMPSCRIPT on the email level?
