CXone OData v2 Agent State History Query Returning Empty Dataset

NICE CXone API & Integrations

Looking for some advice on troubleshooting this query against the CXone Reporting API. I am pulling agent state history for the last 24 hours via my GraphQL gateway, but the OData response is consistently empty.

  1. Construct OData query: /api/v2/analytics/reporting/query?query={"select":["agentId","stateName"],"where":{"operator":"gt","field":"timestamp","value":"2023-10-26T12:00:00Z"}}
  2. Execute POST with valid bearer token.
  3. Receive 200 OK with results: [].

The endpoint works for call volume. Why is the agent state history dataset returning null values for this timeframe?

Check your payload structure. The Java SDK requires specific object types for the query body, not raw JSON strings.

Cause: The query parameter expects a ReportingQuery object, not a stringified JSON.

Solution:

ReportingQuery query = new ReportingQuery();
query.setSelect(Arrays.asList("agentId", "stateName"));
// Build where clause using SDK helpers

This looks like the exact serialization mismatch I hit with Terraform state drift. The Java SDK fix from The point above is correct because sending raw JSON strings causes the API to ignore the filter clauses entirely. I switched to using the SDK’s ReportingQuery builder and got data immediately.

Check your view configuration; agent state history requires view: "agent" not queue.

{
 "view": "agent",
 "select": ["agentId", "stateName"],
 "where": {
 "operator": "gt",
 "field": "timestamp",
 "value": "2023-10-26T12:00:00Z"
 }
}

make sure you set the view to agent as mentioned above, otherwise the api ignores your filters.

query = ReportingQuery(view="agent", select=["agentId", "stateName"])
