CXone Reporting API v2: Real-time queue stats returning stale data or nulls

Pulling real-time queue metrics via the CXone Reporting API v2 is proving tricky. The documentation suggests POST /api/v2/analytics/queues/realtime/query should return current wait times and agent counts, but the response often seems laggy or missing fields entirely. I’m trying to extract waitTime, activeCalls, and agentsLoggedIn for a specific queue ID, but the payload structure isn’t matching what the SDK types expect. Using the standard Node.js fetch wrapper, I’m sending the query with groupBy: ["queue"] and select: ["waitTime", "activeCalls"], yet the returned data array sometimes contains null values for waitTime even when agents are clearly active in the UI. Is there a specific filter or time window I need to set to force a fresh calculation, or is this a known caching issue with the real-time endpoint? The API returns a 200 OK, so it’s not a permission error, but the data quality is suspect. I’ve tried adjusting the interval parameter in the request body, but that seems to only affect historical rollups, not the real-time snapshot.

Here’s the request body I’m using. The from and to timestamps are set to the current time, but I suspect the API might be interpreting this as a historical range rather than a live state. I’ve also checked the metadata in the response, and it shows totalRecords: 1, which is correct for a single queue, but the actual metric values are inconsistent. Sometimes activeCalls is 0 when I know there are 5 calls in progress. This makes it hard to rely on for a real-time dashboard. I’m using the latest version of the CXone reporting SDK, so type definitions should be accurate, but the runtime values don’t match. Any ideas on how to force a fresh query or if there’s a different endpoint that provides truly live stats without the caching delay? The current approach feels like it’s hitting a buffer that updates every few seconds, which is too slow for our use case. I need a way to get the exact current state of the queue, not an approximation. The groupBy clause might be interfering with the real-time aggregation logic, but I’m not sure how to structure the query to avoid it while still targeting a specific queue. I’ve tried removing the groupBy and just passing the queue ID in the filters array, but the response structure changes and some fields disappear entirely. This inconsistency is making it difficult to build a reliable data pipeline. I’m stuck on how to get clean, real-time data without dealing with nulls or stale values. The API seems designed for historical analysis, not live monitoring, but the docs claim otherwise. I’m missing something obvious in the request construction or the interpretation of the response. I need a concrete example of a working request that returns accurate, non-null real-time metrics for a single queue. The current setup is too unreliable for production use. I’m looking for a definitive way to query this endpoint correctly. I’ve spent hours tweaking the parameters, but the results remain inconsistent. I need a working pattern to follow. I’m ready to adjust the code, but I don’t know what to change next. The lack of clear examples in the docs is frustrating. I’m hoping someone has cracked this. I’m open to using a different method if the REST API isn’t suitable. I just need the data. I’m stuck. I need help.

It’s likely that the waitTime field is null because the queue hasn’t had any calls in the last few seconds, which triggers that null state rather than a zero. The API returns nulls for metrics that don’t have current data points, so you’ll need to handle that in your parser. Also, make sure your interval in the request body matches what you’re expecting for “real-time.” If you set it too granular, you might get sparse data. The payload structure in the SDK is strict, so missing fields will throw type errors if you’re using TypeScript. You should check the groupBy array as well. If you’re not grouping by queue or wrapUpCode, the aggregation might not return the specific queue stats you’re looking for. Here is a working payload that usually fixes the null issue by ensuring the correct grouping and a reasonable interval:

{
 "interval": "PT1M",
 "groupBy": ["queue"],
 "select": [
 {"name": "queue.id"},
 {"name": "queue.name"},
 {"name": "agentsLoggedIn"},
 {"name": "activeCalls"},
 {"name": "waitTime"}
 ],
 "where": [
 {"name": "queue.id", "op": "in", "values": ["your-queue-id-here"]}
 ]
}

You’ll also need to ensure your OAuth token has the analytics:query:read scope. Without that, the API might return a 403 or an empty object, which can look like stale data if your error handling isn’t catching the status code. The waitTime metric is specifically tricky because it’s an average, so if there are no waiting calls, it’s null. You’ll want to default that to 0 in your frontend logic to avoid breaking your UI. The agentsLoggedIn count should be accurate though, as long as the agents are actually logged in to that specific queue. If you’re still seeing issues, try querying the agents endpoint directly to verify their status. Sometimes the reporting cache lags slightly behind the live state, especially during peak hours in London time. Check the startTime and endTime in your request too. If they’re too far apart, you’re getting averages, not real-time snapshots. Keep the interval tight for true real-time data.
