Stuck on a weird rate-limiting issue with the REST API action inside Genesys Cloud Architect. Running a load test simulating 200 concurrent calls hitting a specific flow. The flow makes a POST request to an external service, but the Genesys platform itself seems to be throttling the internal API call to the external endpoint before it even leaves the cluster.
Environment details:
- Genesys Cloud instance in
ap-southeast-1 - JMeter
5.6.2with WebSocket plugin - Thread group ramp-up: 0-200 threads over 60 seconds
The error returned in the Architect log is a 429 Too Many Requests with error code platform_api_rate_limit_exceeded. This happens even though the external service has no rate limits. I checked the default API rate limits for the org, but I’m not sure if Architect flows count against the standard platform API limits or have a separate quota.
Is there a specific header or configuration in the REST API action to handle high throughput better? Or is this a hard limit on the number of outbound API calls per second from Architect? The call capacity planning doc doesn’t mention this specific bottleneck.
