Cursor pagination on /api/v2/analytics/conversations/details/query hanging after 10k rows

NICE CXone API & Integrations

Need some help troubleshooting cursor pagination on /api/v2/analytics/conversations/details/query. I’m using the Node.js SDK in a Step Function with maxRecords: 10000 and passing the nextPageToken from the response, but the subsequent request returns a 200 with an empty entities array and no new cursor after exactly 10k records, despite knowing more data exists in the date range. Is this a known limit or am I mishandling the token format? Here’s the loop: while (response.nextPageToken) { response = await client.analyticsApi.getAnalyticsConversationsDetailsQuery({ body: { ...query, from: response.nextPageToken } }); }

Have you tried implementing the GetRESTProxy within a CXone Studio loop to handle the pagination state? The Node.js SDK approach is valid, yet it often encounters transient connection resets or token invalidation when executed within serverless Step Functions. By shifting this logic into a Studio flow, you leverage the platform’s native session persistence.

// Studio Script: Initialize REST Proxy
var restProxy = GetRESTProxy();
var config = {
 method: "POST",
 url: "/api/v2/analytics/conversations/details/query",
 headers: { "Content-Type": "application/json" },
 body: JSON.stringify({
 dateFrom: "{{startDate}}",
 dateTo: "{{endDate}}",
 pageSize: 10000,
 pageToken: "{{pageToken}}" // Dynamic variable
 })
};
var response = restProxy.request(config);
SetVariable("nextPageToken", response.data.nextPageToken);
SetVariable("hasMore", response.data.hasMore);

Ensure you are validating the hasMore flag explicitly. The empty entity array typically indicates the cursor has expired due to the 24-hour window constraint rather than a missing token. Assign the nextPageToken to a dynamic variable before each iteration to maintain state integrity across sub-script calls.

I’d suggest checking out at the pageToken parameter specifically. The Studio suggestion is valid for flows, but in Python, ensure you are passing the token as a query parameter, not in the body. The API rejects body-based tokens with a 400 error. Here is the correct requests implementation:

params = {'pageToken': response.json().get('pageToken')}
requests.get(url, headers=headers, params=params)

The best way to fix this is to stop relying on nextPageToken alone. The suggestion above regarding pageToken is correct, but you must also verify the from and to timestamps remain static. In the Node SDK, conversationsDetailsQuery resets if the window drifts. Use params.from and params.to explicitly.

const params = {
 pageToken: response.nextPageToken,
 from: originalFrom,
 to: originalTo
};

This looks like a misunderstanding of how the Genesys Cloud Analytics API handles cursor pagination versus traditional offset pagination. The /api/v2/analytics/conversations/details/query endpoint strictly enforces a maxRecords limit per request, and while 10,000 is the maximum allowed, the API does not guarantee that a single cursor will traverse the entire dataset if the underlying data volume exceeds internal batching thresholds or if the query filters cause dynamic sharding.

In my experience building enterprise Angular desktop apps that consume these analytics streams via RxJS, the issue is rarely the token format itself, but rather the stability of the query parameters. When you pass nextPageToken, you must ensure that the from and to timestamps, along with any view filters, remain identical across all requests. If your code dynamically recalculates the to timestamp based on Date.now() for each iteration, the API treats it as a new query scope, invalidating the previous cursor.

Here is the correct pattern using the Node.js SDK to ensure parameter stability:

let pageToken = null;
const queryBody = {
 view: 'acd',
 from: '2023-01-01T00:00:00.000Z',
 to: '2023-01-31T23:59:59.999Z',
 maxRecords: 10000
};

do {
 queryBody.pageToken = pageToken;
 const response = await platformClient.analyticsApi.conversationsDetailsQuery(queryBody);
 
 if (response.entities && response.entities.length > 0) {
 // Process entities
 console.log(`Processed ${response.entities.length} records`);
 }
 
 pageToken = response.pageToken;
} while (pageToken);

Warning: Do not use nextPageToken if it is not explicitly returned in the response object. If pageToken is null or undefined, the pagination is complete, even if you suspect more data exists. Verify your date range isn’t being truncated by daylight saving time edge cases, which can cause the API to return an empty set prematurely.
