Could someone explain why we are hitting rate limits on the Quality API endpoints when running a moderate concurrent load? We are setting up a performance baseline for our WFM integration and using JMeter to simulate bulk quality form submissions.
The test is failing consistently after about 500 requests per minute. We are not seeing any issues with call volume APIs, but the Quality Management endpoints seem to have a much stricter throttle.
Here are our environment details:
- Genesys Cloud Region: US-East
- JMeter Version: 5.6.2
- Thread Count: 50 concurrent users
- API Endpoint: POST /api/v2/quality/evaluations
- Error Response: HTTP 429 Too Many Requests
- Retry-After Header: 2 seconds
We have tried adding a random delay between 100ms and 500ms between requests, but the 429 errors still occur. The documentation mentions default rate limits, but it is unclear if there is a specific limit for Quality evaluations versus other admin APIs.
Is there a known workaround or a different approach to handle bulk quality submissions during load testing? We want to ensure the system can handle our peak evaluation periods without blocking the API.
TL;DR: Batch requests to bypass per-request throttling.
I usually solve this by aggregating submissions into a single payload for the bulk endpoint. The standard /quality/evaluations route enforces strict per-minute limits. Switching to /api/v2/quality/evaluations/bulk allows up to 100 items per call, significantly reducing overhead for WFM integrations.
{
"evaluation": {
"formId": "form_123",
"interactionId": "int_456",
"score": 100,
"status": "submitted"
}
}
Make sure you check the specific rate limits for the Quality Management module before ramping up your JMeter threads. The suggestion above about using the bulk endpoint is solid, but there is a catch. In Zendesk, we often handled quality data through simple ticket field updates which were much more forgiving. Genesys Cloud treats quality evaluations as distinct entities with stricter governance.
If you hit the 429 limit, it is not just a throttle; it can lock out your WFM integration for several minutes. I experienced this during our recent migration from Zendesk. The fix is to implement exponential backoff in your script immediately after the first error. Do not retry at full speed. Also, verify that your API user has the “Quality Admin” role, as some lower-tier roles have hidden lower limits on these endpoints. This usually prevents the sudden cutoff.
