Could someone explain why our Genesys Cloud WFM integration is failing specifically during bulk schedule publication events? We have a robust Data Action configured to push schedule changes to ServiceNow for automated ticket creation in our incident management system. The integration works flawlessly for individual agent schedule updates, but as soon as we trigger a bulk publish via the WFM console, the ServiceNow REST API endpoint returns a 502 Bad Gateway error.
The issue appears to be related to the payload size or the concurrent request handling on the ServiceNow side. When a bulk publish occurs in Architect, Genesys Cloud fires multiple webhook events in rapid succession. The ServiceNow instance, which is already under load from other integrations, seems to choke on the sudden spike in incoming requests. We have verified that the ServiceNow instance is healthy and that the endpoint is accessible via direct curl tests with smaller payloads.
“When configuring webhooks for bulk operations, ensure that the target system can handle concurrent requests. Implementing exponential backoff and rate limiting is recommended to prevent overload.”
We have attempted to adjust the retry policies in Genesys Cloud, but the 502 errors persist. The error logs in ServiceNow show that the requests are timing out before they can be processed. We suspect that the issue might be related to the way Genesys Cloud batches the webhook events during bulk operations. Is there a way to configure Genesys Cloud to serialize these requests or introduce a delay between them? Alternatively, are there best practices for handling high-volume webhook events in ServiceNow that we might be missing? We are running Genesys Cloud version 2023-11 and ServiceNow version Washington DC. Any insights or suggestions would be greatly appreciated.
