ServiceNow Integration Failing with 401 Unauthorized via Architect

NICE CXone API & Integrations
1

Could someone clarify why the outbound webhook from Architect is returning a 401 Unauthorized error when calling the ServiceNow REST API? The Basic Auth credentials are identical to the working Postman collection, yet the integration fails consistently.

  1. Architect flow triggers on conversation end.
  2. HTTP Request node sends POST to https://instance.service-now.com/api/now/table/incident.
  3. Payload contains JSON body with short_description and caller_id.
  4. Response returns 401 Unauthorized with no additional details in the logs.
