Stuck on a problem and need help troubleshooting a rate limit issue. Running JMeter 5.6.2 from Singapore to test /api/v2/outbound/campaigns. Single requests work fine. At 50 threads, getting 429 Too Many Requests. The architect flow hangs then fails under load.
My JMeter config uses a constant throughput timer set to 200 samples per minute. The OAuth token is valid and has all necessary permissions. I checked the rate limit headers and see x-ratelimit-remaining dropping to zero quickly.
Is there a specific limit for outbound campaign creation endpoints? The documentation mentions general platform limits but not specific ones for outbound. I tried adding a random delay between 100ms and 500ms but still hit the limit.
The error response body says “Too Many Requests” with no retry-after header. This makes it hard to implement backoff logic. Any ideas on how to handle this for large scale load tests?
