What’s the best way to paginate /api/v2/analytics/conversations/details/query when the cursor parameter returns a 400 Bad Request after the first page?

  1. GET /api/v2/analytics/conversations/details/query with page=1 and pageSize=100. Response includes nextPageToken.
  2. GET /api/v2/analytics/conversations/details/query with cursor={nextPageToken}.
  3. Response: {"errorCode": "bad.request", "message": "Invalid cursor format"}.

The documentation explicitly states, “Use the cursor parameter for subsequent requests to retrieve additional pages of data.” Why does the token fail validation?

If I remember correctly… the cursor parameter is strictly for the older detail queries, but the new analytics endpoints often require specific header configurations. I was hitting the same 400 error last week while building my Spring Boot aggregator. The docs for the Java SDK state: “Use the nextLink from the response object for subsequent requests instead of manually constructing the cursor parameter.”

Here is how I handled it in my service using the PureCloudPlatformClientV2. The key is to use the provided nextLink which contains the necessary encoded parameters, rather than just the token.

ConversationDetailsQueryResponse response = analyticsApi.getAnalyticsConversationsDetailsQuery(...);
while (response.getNextLink() != null) {
 // Use the nextLink URL directly or parse it
 response = analyticsApi.getAnalyticsConversationsDetailsQueryFromUrl(response.getNextLink());
}

Also, ensure your API client handles the connection pooling correctly. If the thread pool is exhausted during these sequential calls, you might see intermittent failures that look like pagination errors. Check your ApiClient configuration for max connections.

Check your pagination strategy. The nextLink approach works, but it’s fragile for IaC syncs. I prefer fetching all IDs first via the summary endpoint, then batch-fetching details. Avoids cursor drift entirely.

const summaryResp = await platformClient.analyticsApi.postAnalyticsConversationsDetailsQuery({ body });
const ids = summaryResp.body.entities.map(e => e.id);

See docs.

this looks like a scope mismatch. you need analytics:conversations:read not just analytics:read or the cursor validation fails silently. check your oauth token scopes.
