CXone Personal Connection outbound call 401 error

Attempting to trigger an outbound call via the CXone Personal Connection API. The request hits POST /api/v2/outbound/calls but returns a 401 Unauthorized. I have verified the OAuth token is valid for other endpoints.

{
 "contactId": "12345",
 "campaignId": "67890",
 "connectionId": "abc-def"
}

Is there a specific scope required for this endpoint?

That endpoint isn’t standard CXone. Personal Connection sits on Genesys Cloud. You’ll need conversation:write scope, not outbound. Try /api/v2/conversations/calls with a proper to address in the payload. The 401 is likely a missing scope for the wrong API path.
