Agent Scripting API 429 during JMeter load test on US1

Does anyone understand why the Agent Scripting API returns 429 Too Many Requests when JMeter hits 50 concurrent threads? We are testing script playback start/stop endpoints on Genesys Cloud US1. The flow is simple, just triggering playback via REST. Rate limits seem too low for our load requirements.

  • Checked standard rate limit docs, but no specific guidance for scripting endpoints.
  • Reduced thread count to 20, which works, but fails at 50.
