Analytics API 429s during JMeter ramp-up for call volume metrics

Anyone free to help troubleshoot this spike in 429 Too Many Requests errors when pulling real-time analytics data via the Genesys Cloud API. We are running a JMeter script to validate how the reporting stack handles concurrent requests for call volume metrics.

The issue starts when we ramp up to 50 concurrent threads hitting the analytics conversation summary endpoint. The response headers show retry-after values that fluctuate wildly, breaking our fixed-loop logic. We are using the standard OAuth2 client credentials flow and have verified the scope includes analytics:reports:read.

The environment is a standard Genesys Cloud instance in the Singapore region. We are not seeing any 5xx errors, just strict rate limiting. Is there a specific endpoint we should be using for high-throughput polling, or is this expected behavior for the summary endpoint under load?
