I Can't AddRequest By Api

I really don't know what to do anymore!

Based on the recommended structure noted in service desk plus documentation for "addrequest" by API

{
    "request": {
        "subject": "Unable to fetch mails",
        "description": "I am unable to fetch mails from the mail server",
        "requester": {
            "id": "66007",
            "name": "Morteza Khorsand"
        },
        "resolution": {
            "content": "Mail Fetching Server problem has been fixed"
        },
        "status": {
            "name": "Open"
        },
        "category": {
            "name": "MyATC Helpdesk"
        }
    }
}

- in which tab of Postman authorization should be added?

- which part of the above structure is wrong, resulting this error:
{

    "response_status": {
        "status_code": 4000,
        "messages": [
            {
                "status_code": 4001,
                "field": "input_data",
                "type": "failed",
                "message": "Value not provided"
            }
        ],
        "status": "failed"
    }
}
