Analytics API 429 Rate Limit During High-Volume JMeter Spike

Hitting a wall with the Analytics API during our latest load test. When JMeter threads exceed 50 concurrent requests to /api/v2/analytics/conversations/details/summary, the response shifts from 200 OK to 429 Too Many Requests. The header x-rate-limit-remaining drops to zero quickly, and subsequent calls are blocked for 60 seconds. This is breaking our automated reporting pipeline which expects real-time data every 5 minutes.

Current JMeter config:

  • Thread Group: 100 users
  • Ramp-up: 10 seconds
  • Loop Count: Forever
  • Request: POST /api/v2/analytics/conversations/details/summary

Payload sent:

{
 "query": {
 "date_from": "2023-10-25T00:00:00Z",
 "date_to": "2023-10-25T23:59:59Z",
 "granularity": "FIFTEEN_MINUTES"
 },
 "fields": ["wrap.up.code", "conversation.duration"]
}

Is there a specific header or retry logic I should implement to handle this better? Or is there a higher tier API endpoint for bulk historical data that doesn’t have this strict per-second limit? We are testing peak volume scenarios for Q4 planning and this bottleneck is critical. Environment is Genesys Cloud US East, version 2023-10-25.
