Sorry if this has been asked before.
I was wondering if the API can use a Segment of a list, or will I just have to create whole separate lists and manage them separately? I wanted to maintain a nice clean list of select multiple type of Custom Fields, and then be able to utilize the subscriber preferences to basically join/leave various segments. Without it I'd have to code my own preference screen to join/leave separate lists.
That also makes me wonder how i could utilize the flat monthly costs when I may have about 50 lists to use.
I'm happy to say that we'll be releasing our REST api very shortly, which will have an extensive range of routes for creating and working with segments.
Keep watching the forums, we'll be sure to make an announcement soon.
