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 hit /api/v2/architect/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/architect/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.
