  description: 'Read and write user activity, exercise, and Active Zone Minutes (AZM) data on

    Fitbit. The Activity API exposes daily activity summaries (steps, distance,

    calories, floors, elevation, activity minutes), per-activity logs, lifetime

    totals, activity goals, the user''s exercise type catalog, and Active Zone

    Minutes time series. Time-series endpoints accept a base-date and either an

    end-date or a period (1d, 7d, 30d, 1w, 1m, 3m, 6m, 1y).
