In the last Marketing Cloud release there is the new transactional messaging API option (https://developer.salesforce.com/docs/atlas.en-us.mc-apis.meta/mc-apis/transactional-messaging-api.htm).
Before we want to enable this option we wondered what this new API call is doing exactly other then a standard normal API call. Why should we use this new API call instead of the standard (server to server) API integration? Is there someone allready use this new option?
