Stuck on a timeout mismatch between Genesys Cloud Architect and ServiceNow.
Environment: Genesys Cloud EU1, ServiceNow London instance.
Flow: Post-call Data Action triggers a ServiceNow REST API to create an incident record based on conversation metadata.
The issue manifests as a 504 Gateway Timeout returned by the Data Action step in Architect, yet the incident is successfully created in ServiceNow. The ServiceNow side logs show the request was processed in roughly 4 seconds. Genesys Cloud Architect Data Actions have a default timeout of 30 seconds, which should be sufficient. However, the timeout seems to occur consistently when the webhook payload exceeds a certain size, particularly when including full transcript data.
Environment details:
- Genesys Cloud Region: EU1
- ServiceNow Instance: London
- Data Action Type: REST API Call
- Payload Size: ~45KB (including transcript)
- Timeout Error: 504 Gateway Timeout
Has anyone encountered similar latency issues with large webhook payloads in Data Actions? Are there specific payload size limits or timeout configurations that need adjustment to prevent this false timeout? The goal is to ensure reliable ticket creation without data loss or false failure indicators in the Architect flow.
I’d recommend looking at at how the timeout is configured in the Data Action step versus the actual processing time on the ServiceNow side.

This discrepancy usually points to a mismatch in how Genesys Cloud handles the response window. The default timeout for a Data Action in Architect is often set quite low, sometimes around 5 seconds, but network latency between EU1 and London can eat into that budget quickly. If the ServiceNow API takes 4 seconds to process, plus network overhead, you are likely hitting the hard limit on the Genesys side before the 200 OK response arrives.
In load testing scenarios, we often see this exact pattern. The request goes through, but Genesys Cloud drops the connection because it did not receive a timely acknowledgment. To fix this, adjust the timeout setting in the Data Action configuration within Architect.
- Open the Flow in Architect.
- Select the Data Action step.
- Increase the “Timeout” field. Try setting it to 10 or 15 seconds initially to see if the error persists.
Also, check if the ServiceNow endpoint is doing any synchronous heavy lifting. If it can return a 202 Accepted immediately and process the incident asynchronously, that would be more robust for high-concurrency environments. This prevents Genesys Cloud from waiting unnecessarily.
Here is a sample JMeter test plan snippet to verify the latency:
<HTTPSamplerProxy guiclass="HttpTestSampleGui" testclass="HTTPSamplerProxy" testname="ServiceNow Check">
<stringProp name="HTTPSampler.domain">your-instance.service-now.com</stringProp>
<stringProp name="HTTPSampler.path">/api/now/table/incident</stringProp>
<intProp name="HTTPSampler.timeout">15000</intProp>
</HTTPSamplerProxy>
Monitoring the actual round-trip time helps distinguish between a Genesys configuration issue and a ServiceNow performance bottleneck. Adjusting the timeout usually resolves the 504 immediately.
