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.
Response headers
Weak entity tag of the body. Send it in If-None-Match on the next request.
Response
Headline call KPIs. Call-activity numbers (interactions, outcomes, sentiment, duration,
channel breakdown) cover the requested window and filters. Entity counts (agents,
campaigns, contacts) are workspace-wide totals that ignore the window and every filter.
Counts and rates are 0 when there is no data; averages are null.
