Having some issues getting my configuration to work… Getting HTTP 500 Internal Server Error on /api/v2/conversations/messages when JMeter sends 50 concurrent bot init requests. The error stops if I drop threads to 10. Checking Genesys Docs but no mention of bot throughput caps. Region is us-east-1.
Check your rate limiting configuration and the specific error payload. The 500 error often masks a 429 Too Many Requests or a backend timeout when the bot flow logic exceeds the default conversation service thresholds. The Genesys Cloud Conversations API has strict limits on message ingestion per organization, not just per endpoint. When JMeter spikes to 50 concurrent threads, you are likely hitting the global org-level cap or the specific bot flow execution limit.
First, inspect the response body of the 500 error. It usually contains a message field explaining the actual cause, such as “Rate limit exceeded” or “Internal processing error due to timeout.” If it is a rate limit, you need to implement exponential backoff in your JMeter script or use the Genesys Cloud CLI to monitor current throughput limits.
If the error persists after adding delays, the issue might be within the bot flow logic itself. Complex flows with many decision points or external API calls can timeout under load. Ensure your bot flow uses async data actions where possible. Sync calls block the conversation thread and increase the chance of a 500 error during high concurrency.
Here is a snippet to check your current rate limit status using the Genesys Cloud CLI:
genesys cloud analytics:report:query -q "conversation:messages:total" -f 5m
Also, verify that your bot is not making synchronous calls to external systems that have their own rate limits. If the external system responds slowly, the Genesys Cloud bot flow will wait, consuming resources and potentially timing out.

- Bot flow execution timeouts
- Async vs. sync data actions in CX as Code
- JMeter concurrency settings for API testing
