I would need to integrate a transactional event with a new field on Adobe Campaign Standard that should then be passed within a landing page built on the Campaign. Does anyone know if it is possible to do it and how could it be implemented?
I don't think it's possible to integrate real time transactional event field on landing page. Since landing page will work ONLY with profile and service resources. If you're having profile based transactional event then it's possible since you will have all of the fields from profile resource.
