What’s the best way to query agent state history for the last 24 hours using CXone Reporting API v2? 400 Bad Request on POST /api/v2/reporting/agentstatedetails/query when sending {"dateFrom": "2023-10-26T15:00:00+09:00", "dateTo": "2023-10-27T15:00:00+09:00"}.

This looks like a timezone serialization issue.

  • Use UTC strings without offset. The API expects 2023-10-26T15:00:00Z.
  • Wrap the call in a retry decorator. Reporting endpoints are volatile.
  • Validate the payload against the OpenAPI spec before sending.
query = {"dateFrom": "2023-10-26T15:00:00Z", "dateTo": "2023-10-27T15:00:00Z"}

TL;DR: The suggestion above is correct, but don’t stop there.

Check your dateFrom and dateTo against the 24-hour window limit. The reporting API rejects ranges >24h with a 400, regardless of format.

// Ensure delta <= 24h
const start = new Date('2023-10-26T15:00:00Z');
const end = new Date('2023-10-27T15:00:00Z');
if (end.getTime() - start.getTime() > 24 * 60 * 60 * 1000) throw new Error('Range exceeds 24h');
