List daily call metrics
Authentication
Query parameters
Size of the reporting window in days, ending now. On most analytics routes a missing or out-of-range value falls back to 30 instead of being rejected; the operation says when it is strict.
Which calls to count: inbound (calls the agent answered), outbound (calls the agent placed) or all (both).
Scope every number to one agent — the agent that served each call, so manual (campaign-less) calls count. Omit it to aggregate across agents.
IANA time zone the day and hour buckets are computed in (default UTC). An unknown zone falls back to UTC; a value longer than 50 characters is rejected with 400.
