API V3 worklog issue 10.6 Build 10601

API V3 worklog issue 10.6 Build 10601

Hi,
We upgraded the Dev server on 10.6 build 10601. And in previous build 10.4, I had a call on v3 api that was working for fetching worklogs from request with a call on /api/v3/requests/xxxxx/worklog

When calling now the service I get an issue :
{
    "response_status": {
        "status_code"4000,
        "messages": [
            {
                "status_code"401,
                "type""failed",
                "message""V3API restricted for Path:/api/v3/requests/47074/worklog Method:GET"
            }
        ],
        "status""failed"
    }
}
I read that some changes has been made on the API but how can I solve the above issue ?
Thanks
