Summary

Unable to Query an Employee using cloud HCM REST API

Content

Hello experts,

got below error when I tried invoking Employee REST GET method using SoapUI

HTTP/1.1 403 Forbidden

Here is the URL I am using: https://<****-xxxxxx.xx.xx>.oraclecloud.com/hcmRestApi/resources/11.13.17.11/emps?q=PersonId=<NNNNN&gt;

the PersonId that I am using exists in the system and my user has access to fetch this person's details online as well as in SOAP service UserDetailsServiceV2 (findUserDetailsByPersonId method)

Also, I am able to access other REST services such as locations and organizations on the same cloud instance without any trouble.
