Running a JMeter 5.6 load test to validate SMS throughput on Genesys Cloud US1. Goal is to simulate 200 concurrent outbound messages via POST /api/v2/conversations/messages. After 3 minutes of steady state, hitting 429 Too Many Requests errors. Rate limit headers show x-rate-limit-remaining hitting zero. Is there a specific burst limit for messaging APIs? Current config uses thread group with 5s ramp-up. Any tips to avoid throttling?
This falls outside the scope of performance dashboarding and queue activity analysis. For API rate limiting specifics, consult the developer documentation or engage a technical architect familiar with RESTful endpoint constraints.
The 429 response confirms you have exhausted the endpoint’s rate limit, not a burst cap. For load testing, avoid direct POSTs to /api/v2/conversations/messages. Instead, simulate via the IVR or use the Asynchronous Messaging API if available. Direct high-concurrency writes will always throttle. Check the Retry-After header to adjust your ramp-up strategy accordingly.
