WFM API 429s when bulk-creating evaluation templates for load test

Just noticed that the WFM Quality Management APIs are throttling us during our infrastructure stress tests. We are trying to pre-populate evaluation templates via the platform API to simulate a high-volume QA review cycle. The endpoint is POST /api/v2/wfm/quality/evaluation-templates.

Using JMeter with 50 concurrent threads hitting the endpoint at roughly 10 req/s. After about 30 seconds, we start receiving 429 Too Many Responses with the header Retry-After: 60. The standard documentation mentions rate limits, but for a bulk creation scenario during setup, this feels restrictive. We aren’t hitting this on the telephony APIs, which handle much higher throughput.

Is there a specific header or pagination strategy that helps bypass this for batch operations? Or is this a hard limit for the WFM domain specifically? We need to generate ~500 templates within a 5-minute window for our test data setup. Currently, we are forced to serialize the requests, which adds significant overhead to the test initialization phase. Any workarounds appreciated.
