Hi
I am sure, we can do this for-sure. As the target framework in AEM is also communicating with Adobe Target using its API's (back-end level). So if you need to implement some custom component or service in AEM communicating with Target then you need to use Adobe Target API's [1]. I don't think AEM provide any wrapper API's on top on Target's API.
But what exactly is the use-case to communicate with Target without using target framework in AEM ?
