We recently gained access to the Transactional Messaging API for our MID. During testing we successfully created a send definition but are unable to find the location of the send definition in the UI. Unlike other triggered sends, the send definition does not appear to be located in any folder of 'Triggered Emails' in the 'Interactions' tab of Email Studio. And while we were able to successfully trigger an email with the API, no tracking record appears to have been created.
Does anyone know where these two assets would be placed? Documentation around the Transactional messaging API is incredibly sparse.
