Groups
A group is who a group-scoped event is about. A static group keeps a list you add to; a dynamic group holds whoever's attributes contain its filter, so nobody keeps it up. Beside the groups somebody keeps are temporary lists, picked by a person for one send: you can see them, but a key cannot change one and an event cannot name one. In the Political party pack a group is, for example, “Montserrado County”.
GETList who is in a group
Requires groups:read. The memberships a static group lists — or people, for a group of people — whole. A dynamic group keeps no list, and an empty one here would read as “nobody is in it”, so it is refused: ask /matches.
200 with an array of memberships or people. 400 on a dynamic group.
A bare JSON array. Each item is one membership: the same fields in every pack. Press Response on the sample to see one whole.
On failure the body is { error, code } instead.
