Architect Webhook 408 Timeout on ServiceNow PII Redaction

Just noticed that the outbound webhook from our Genesys Cloud Architect flow to ServiceNow is timing out with a 408 Request Timeout when attempting to create an incident record containing redacted PII fields. The flow uses the Data Actions module to transform the payload before sending to api/now/table/incident. The latency exceeds the 3000ms threshold, causing the SIP trunk registration to drop. Any insights on optimizing the payload size or handling synchronous webhook callbacks more efficiently?
