Data Action Timeout Handling in High Load

• Is there a clean way to handle 504 Gateway Timeout errors from a downstream Data Action endpoint when running concurrent load tests?
• JMeter script pushes 1000 threads/sec to Genesys Cloud.
• Data Action calls a custom integration endpoint.
• Timeout occurs at 10 seconds.
• Do I need to increase the timeout in Architect or handle retries on the integration side?

Have you tried decoupling the synchronous call from the immediate user experience? In Zendesk, we relied heavily on triggers and webhooks that ran asynchronously, so a slow external API didn’t freeze the agent’s UI. Genesys Cloud’s Data Actions in Architect are synchronous by default, meaning a 10-second timeout blocks the entire flow execution.

Instead of increasing the timeout, which risks cascading failures under high load, consider using a “Queue and Forget” pattern. Trigger the external process via a separate webhook or queue mechanism, then return a success status to the Architect flow immediately. This mirrors the shift from Zendesk’s event-driven macros to Genesys’s real-time flow logic.

If you must keep it synchronous, ensure your integration endpoint is optimized for sub-200ms responses. Below is a comparison of the timeout behaviors:

Refactor the integration to handle retries internally, not in the flow.
