Unable to Authenticate Oracle EPM REST APIs Using Groovy Named Connection (HTTP 401 OAuth Redirect)

Summary:

Unable to authenticate Oracle EPM REST APIs from FCCS/TRCS Groovy using a validated Named Connection. All REST API calls return either HTTP 401 (Authorization Required) or redirect to Oracle Identity Cloud Service (OAuth authentication endpoint). Looking for confirmation whether Interop APIs (SkipUpdate, Applicationsnapshots, etc.) are supported through Groovy Named Connections.

Hello Experts,

We are attempting to automate the Oracle EPM Skip Update process using a Groovy business rule and a Named Connection instead of EPM Automate.

Objective

Call Interop REST APIs from a Groovy rule using:

def conn = operation.application.getConnection("FCCS")
