POST/api/v1/schedules/{id}/layers

Adds a rotation layer. A layer runs its people in turn, handing over every day or week from rotation_start (default: now; an unreadable value is ignored). Restrict it to a shift — certain weekdays and a time window in the schedule's timezone — with the three restrict_* fields; a window may cross midnight. Leave them out for a layer that covers all day, every day.

A schedule that belongs to a team is visible only to callers in that team (and to administrators acting in person); others get 404, as if it did not exist.

Permission (API-key scope): oncall:schedule:write.
