Not sure if I'm missing something here, but is there a way to get a list of all subscribers in a list through the API regardless of their status (subscribed, unsubscribed)?
Or is this the Subscribers.GetActive method? (How do you define active)?
There's not a single call where you can get all the active and inactive (unsubscribed, bounced, etc) in a list. You'd have to do separate calls for each type and put your list together: For active subscribers (not bounced, not unsubscribed) you would use Subscribers.GetActive, for bounced Subscribers.GetBounced, and for unsubscribed Subscribers.GetUnsubscribed.
