Hi,
because I looking for a low level solution, where a campaign sends a mail to e.g. a sales person for them to to a decision, which influences the campaign for a particular lead. Its not the first time this requirement comes up from my clients… It would be easy to generate this link within a simple button.
If I work with the API just for this scenario, I need to have one more active component to be setup and maintained 
So did I missunderstand the Call to /mtc/event/ ? I was successful with “page_hit” and “tags”. But not with matching the contact ID / email.
