Hey everyone, I’ve run into a really strange issue with BYOC webhook payloads failing to trigger the ServiceNow Data Action. The Architect flow logs show conversation:wrap-up, but the ServiceNow MID server receives a null participantId. This breaks the screen pop logic entirely.
“Ensure the webhook payload includes the full participant context for downstream integrations.”
We are using GC API v2 in EU1. Is there a known latency issue with BYOC events propagating to Data Actions?
Check your webhook configuration in the Architect flow, specifically the Webhook action settings. When migrating from Zendesk, it is easy to assume the payload structure mirrors the ticket update events, but Genesys Cloud handles BYOC sessions differently. The participantId often becomes null if the webhook triggers before the Wrap-up data is fully populated in the interaction object.
In Zendesk, we relied on immediate ticket metadata, but GC requires explicit data mapping. Ensure you are pulling the Participant ID from the interaction context rather than the event payload directly. A common fix is adding a Delay of 500ms before the webhook call to allow the EU1 tenant to synchronize the BYOC session details. Also, verify that your ServiceNow Data Action is configured to handle the specific JSON structure of the conversation:wrap-up event, as it differs significantly from standard digital channel updates. This usually resolves the null pointer issue during screen pops.
If I remember correctly…
Cause:
The null participantId in the ServiceNow MID server payload typically stems from a timing mismatch rather than a data loss. The conversation:wrap-up event fires immediately upon agent action, but the participant context within the interaction object may not have fully resolved in the EU1 region before the webhook executes. This is particularly common with BYOC integrations where external signaling paths introduce slight latency.
Solution:
Instead of relying on the immediate webhook trigger, configure a Wait action in the Architect flow for 2-3 seconds before the Webhook. Alternatively, query the Interaction API directly using the interactionId from the initial webhook to fetch the resolved participant data. Ensure your Partner App service account has interaction:read permissions. This approach guarantees the payload contains the full context required for the ServiceNow screen pop, avoiding the race condition inherent in the default event stream.
