Deciding between /api/v2/conversations and /api/v2/analytics/conversations for real-time agent desktop data

I’ve been digging through the Genesys Cloud API docs for a while now, trying to pin down the exact use case for pulling conversation data into our custom agent desktop app. The main confusion is the split between the /api/v2/conversations endpoints and the /api/v2/analytics/conversations endpoints. Both seem to return similar data structures, but the performance and data freshness are totally different.

Here’s what I’ve tried so far:

  1. Used GET /api/v2/conversations/{id} to pull live data. It’s fast, usually under 200ms, and returns the current state of the interaction. Perfect for screen pops that need to update in real-time.
  2. Tried GET /api/v2/analytics/conversations/details for the same ID. The response takes about 2-3 seconds, and sometimes the data is slightly stale if the conversation just wrapped up.

The issue is that our app needs to display historical context (like previous interactions in the last 24 hours) alongside the current live session. The analytics endpoint is the only one that reliably gives me that historical window in a single call, but the latency is killing the UI responsiveness. The real-time endpoint doesn’t seem to have a built-in way to fetch “past 24 hours” without hitting the limit or making multiple calls.

I tried batching calls to the analytics endpoint, but the 429 Too Many Requests errors start piling up when agents switch contexts quickly. Here’s a snippet of the analytics call I’m making:

GET /api/v2/analytics/conversations/details?query=filter:interaction.id eq "12345"

The response payload is huge and includes metrics I don’t even need, just to get the basic transcript and disposition. Is there a recommended pattern for this? Should I be caching the analytics data on the client side and only hitting the real-time API for live updates? Or am I missing a specific parameter in the analytics query that makes it faster? The docs aren’t super clear on when to pick one over the other for a custom client app scenario.
