Could someone explain the rate limiting thresholds for the Predictive Routing campaign API when initiating bulk outbound calls? We are hitting 429 errors consistently after 500 concurrent requests in the US1 environment using Genesys Cloud SDK 2.3.0.
HTTP/1.1 429 Too Many Requests
Retry-After: 60
The load test script is simple, just triggering startCampaign endpoints. Need to know if this is a hard limit or if our JMeter threading model is incorrect.
