What is the standard approach to map the conversation ID from an outbound dialing completion event to a ServiceNow incident via a Data Action webhook?
We are running an outbound campaign in the EU1 region using Genesys Cloud Architect flows. Upon campaign completion, a webhook is triggered to create a record in ServiceNow for post-call analysis. The payload includes the conversationId and campaignId. However, the ServiceNow REST API endpoint returns a 400 Bad Request error, citing an invalid conversationId format in the JSON body.
The webhook payload structure matches the documentation for conversation.completed events. The issue persists even when using the raw id field from the event payload. Debug logs show the Data Action executes, but the HTTP response from ServiceNow indicates the UUID format is malformed or missing hyphens, despite the source data being a standard UUID.
Is there a known transformation issue with outbound conversation IDs when passed through Data Actions? The environment uses Genesys Cloud version 2023-11. The ServiceNow instance is London timezone aligned. Checking the raw webhook payload via a temporary logging endpoint shows the ID is present but appears truncated after the Data Action processing step.
Check your outbound campaign configuration in the Architect flow, specifically the data mapping for the completion event.
Cause:
The 400 Bad Request error from ServiceNow often stems from a mismatch in the payload structure expected by their REST API, rather than a failure in the Genesys Cloud webhook itself. In the EU1 environment, outbound campaigns generate specific metadata that must be explicitly mapped before the Data Action is triggered. If the conversationId is passed as a raw string but ServiceNow expects a specific JSON object format or a different field name (e.g., genesysConversationId), the API will reject the request. Additionally, ensure that the webhook timeout settings are aligned with ServiceNow’s processing limits, as excessive latency can cause session drops before the incident record is fully created.
Solution:
Review the Data Action configuration in Architect. Instead of passing the conversationId directly, construct a JSON body that matches ServiceNow’s incident creation schema. Use the following structure in the Data Action payload:
{
"short_description": "Post-call analysis for Campaign {{campaignId}}",
"u_genesys_conversation_id": "{{conversationId}}",
"u_campaign_id": "{{campaignId}}",
"state": 1
}
Validate the field names against your ServiceNow table schema. The u_genesys_conversation_id custom field is often required for traceability. Also, verify that the outbound flow includes a “Set Variable” step to capture the conversationId correctly before the Data Action. If the issue persists, enable logging on the Genesys Cloud side to inspect the exact payload being sent. This approach ensures data integrity and aligns with best practices for integrating outbound metrics with external ticketing systems. Monitor the performance dashboard for any spikes in failed webhooks after implementing these changes.
