Need help troubleshooting WFM API 429 errors during load test

Need some help troubleshooting…

  • JMeter 5.6.2
  • Genesys Cloud WFM APIs
  • Asia/Singapore region
  • 20 concurrent threads
  • Testing /api/v2/wfm/schedules/query

Running a basic load test to validate schedule retrieval capacity. Hitting the WFM schedule query endpoint with 20 threads from Asia/Singapore. Getting 429 Too Many Requests errors after about 10 seconds. The response headers show Retry-After: 5 but the errors keep coming even with pauses.

Is there a specific rate limit for WFM APIs that is lower than the general Platform API limits? The documentation mentions general rate limits but nothing specific to WFM endpoints. The test script is simple - just GET requests with valid auth tokens. No complex payloads.

The goal is to understand if 20 concurrent requests is too high for WFM endpoints or if there is something wrong with the request format. The same setup works fine for analytics APIs but fails consistently with WFM endpoints.

Any advice on the correct approach for testing WFM API capacity? Should I be using a different endpoint or adding specific headers?
