HTTP 429 Too Many Requests.
Running a load test on Workforce Management schedule imports. Using JMeter 5.6 to simulate bulk schedule creation via /api/v2/wfm/schedules.
The environment is US1.
We hit the rate limit at 50 concurrent threads. This is much lower than expected for an admin API.
The response header shows ‘Retry-After: 60’.
This breaks our capacity planning for end-of-month schedule updates. We need to support 500 users updating schedules in a short window.
Is this a hard limit for the WFM API? Or is there a different endpoint for bulk operations that handles higher throughput?
We are using the standard REST client. No SDK. Just raw HTTP requests.
Any advice on how to structure the load test to avoid 429s? Should we implement exponential backoff in JMeter? Or is there a specific rate limit documentation for WFM endpoints that we missed?
Thanks for the help.
