Stuck on 429s when testing IVR flow via API

stuck on getting 429 errors when trying to update ivr flows via api during load test.

running jmeter script to update flows. trying to simulate 50 concurrent updates to test rate limits before peak hours. env is production sandbox.

the docs say 100 req/sec but i get throttled way earlier. maybe around 20 req/sec?

here is the jmeter config i used:

  • thread group: 50 users
  • ramp up: 10s
  • loop count: 10
  • http request sampler: put /api/v2/flows/{flowId}

getting this error:
{
“message”: “too many requests”,
“code”: “too_many_requests”
}

is there a way to bypass this for testing? or am i hitting a different limit? also noticed websocket connections drop if i push too hard on the flow updates. not sure if related.

any help appreciated. tired of guessing the limits.
