New endpoints — Rewards points, history and ranking
Three read-only endpoints now expose the center's Rewards data: the current points
balance of every member (GET /api/v2/rewards/members, paginated), the points history
of a member (GET /api/v2/rewards/members/{idMember}/history) and a ranking of members by
the points earned since a date, up to one year back (GET /api/v2/rewards/ranking).
