Genesys Cloud Analytics API: Cursor pagination vs page numbers in /api/v2/anversations/details/query

I’m refactoring our Android app’s analytics dashboard to pull conversation details directly from Genesys Cloud. Previously, we were using a simple page-based approach, but the docs for /api/v2/analytics/conversations/details/query suggest using pageSize and page parameters. However, I noticed that when the dataset gets large, the nextPage token in the response is a cursor string, not a page number.

Here’s the Kotlin code I’m using for the initial request:

val request = AnalyticsQueryRequest()
 .pageSize(100)
 .page(1)
 .dateRange(AnalyticsDateRange().startDate("2023-10-01T00:00:00.000Z").endDate("2023-10-02T00:00:00.000Z"))

val response = analyticsApi.getAnalyticsConversationsDetailsQuery(request)

The first call works fine. I get a nextPage value like eyJpZCI6IjEyMyJ9. My question is: should I be passing this cursor back as the page parameter in the next request, or is there a different header or parameter I need to use?

I tried passing the cursor string into page() again, but the API returns a 400 Bad Request with "message":"Invalid page number". If I use nextPage as a query parameter directly, it seems to work, but the SDK doesn’t expose a nextPage setter on the request object.

Is there a recommended pattern for handling this in Kotlin? Should I be using OkHttp directly to append the nextPage query param, or is there a way to do this with the official SDK without breaking the abstraction? I want to avoid hitting rate limits, so I need to make sure I’m paginating correctly.

Also, does the cursor expire? I’m caching the response for offline viewing, and I’m worried the next page link might become invalid if the underlying data changes. Any insights on the stability of these cursors would be appreciated.

You are probably mixing up the request parameters with the response handling. The docs for /api/v2/analytics/conversations/details/query explicitly state that you should send pageSize and page in the initial request, but you must ignore page in subsequent requests if a nextPage token is present.

The gotcha here is that nextPage is a cursor string, not an integer. If you keep incrementing page, you’ll miss data or hit duplicate records because the cursor encodes the exact position in the dataset, including any changes that might have occurred during the query window.

In C#, I usually handle this by checking the NextPage property on the response. If it’s not null, I use it as the page parameter for the next call, effectively treating the cursor as the page identifier. Here’s how I structure it in my Azure Functions:

var nextPage = "1"; // Start with page 1
var allConversations = new List<ConversationDetail>();

do
{
 var query = new AnalyticsApi.QueryConversationsDetailsRequest
 {
 PageSize = 100,
 Page = nextPage
 };

 var response = await _analyticsApi.PostAnalyticsConversationsDetailsQueryAsync(query);
 
 if (response.Body != null && response.Body.Entities != null)
 {
 allConversations.AddRange(response.Body.Entities);
 }

 // Use the cursor if available, otherwise break
 nextPage = response.NextPage ?? null;
} while (!string.IsNullOrEmpty(nextPage));

The response.NextPage contains the cursor string. If you try to parse it as an int or ignore it, your pagination will break. Also, make sure you’re using the correct OAuth scope, usually analytics:read, or you’ll get 403s instead of data. The cursor approach is safer for large datasets because it handles data shifts better than simple page numbers.
