Classes
A class is who a group-scoped event is about. A static class keeps a list you add to; a dynamic class holds whoever's attributes contain its filter, so nobody keeps it up. Beside the classes 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 High school pack a class is, for example, “5A”.
GETList who is in a class
Requires groups:read. The students a static class lists — or parents, for a class of parents — whole. A dynamic class 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 students or parents. 400 on a dynamic class.
A bare JSON array. Each item is one student: the same fields in every pack. Press Response on the sample to see one whole.
On failure the body is { error, code } instead.
