Querying agent utilization metrics by 30-minute intervals via Analytics API

NICE CXone API & Integrations

How should I properly to retrieve tHandle, tAcw, and tHold metrics broken down by 30-minute intervals using the Genesys Cloud Analytics API?

  1. I am calling POST /api/v2/analytics/queues/details with interval=PT30M.
  2. I am setting metrics to include tHandle, tAcw, and tHold.
  3. The response returns aggregated totals instead of time-bucketed data for each interval.

Is there a specific groupBy parameter or request body modification required to force interval-level granularity for these agent-specific metrics?
