I'm attempting to add a set of leads to a test drip campaign that I set up. Looking through the API documentation and googling around, I am coming up short on answers. Is there a way to do this with the API? So far all the instructions I've seen do so through the web UI.
If there isn't a way to do it through the API, do I need to set a flag on the lead and then use a secondary campaign to push them in? Or some other automated way?
