Analytics API paging behavior with pageSize and pageCount

Is it possible to predict the final pageCount before exhausting all results in the Analytics API? My GraphQL gateway uses DataLoader to batch calls to /api/v2/analytics/conversations/summary. I encounter inconsistent pagination behavior when setting pageSize=1000.

  1. Request returns pageSize=1000 and pageCount=5.
  2. Fetching page 5 returns only 50 records.
  3. Page 6 returns empty results.

Why does pageCount overestimate total pages? How should I handle the last page in the resolver?

You should probably look at at the analytics endpoints are cached so they lag during k6 spikes. try the websockets api instead for real-time data…

It depends, but generally you cannot reliably predict the final pageCount before exhausting results because Genesys Cloud’s analytics engine calculates pagination dynamically based on real-time data availability and shard distribution. The discrepancy you’re seeing between pageSize=1000 and pageCount=5 is likely due to how the backend splits large result sets across time intervals. Instead of relying on pageCount for DataLoader batching, I recommend implementing a cursor-based pagination approach in your CLI wrapper. This avoids the “empty page” issue entirely. Here is how I handle it in my Python CLI using Typer and the PureCloud SDK:

from genesyscloud.platform_client_v2 import PlatformClient
from genesyscloud.analytics.rest import AnalyticsApi

def fetch_conversations_summary(platform_client: PlatformClient, page_size: int = 1000):
 analytics_api = AnalyticsApi(platform_client)
 all_data = []
 page_number = 1
 while True:
 response = analytics_api.post_analytics_conversations_summary(
 body={"pageSize": page_size, "pageNumber": page_number}
 )
 if not response.data or len(response.data) == 0:
 break
 all_data.extend(response.data)
 if len(response.data) < page_size:
 break
 page_number += 1
 return all_data

This ensures you fetch all data without guessing the total pages.

const { body } = await platformClient.AnalyticsApi.getAnalyticsConversationsSummary({
pageSize: 1000,
page: 6
});
if (body.pageCount < 6) break; // Stop early

The suggestion above highlights the dynamic nature of pagination. I add that you should explicitly check if the requested page exceeds `pageCount`. This prevents unnecessary empty fetches in DataLoader, ensuring your batching logic terminates cleanly without hitting the API for non-existent pages.

Have you tried validating the OAuth token scope? Audit automation requires analytics:read. If your token lacks this, paging logic fails silently.

  1. Check token scopes.
  2. Retry with analytics:read.

Note: Ensure your client ID has analytics:read permissions in the security settings.
