Problem get attachment data on execReportAPI

Hello, i am working with wialon hosting and now i'm facing these problems to get some data :

1. How can i add more paramaters when i get avl_unit, eg: (Vehicle Type : Bus)
2. How can i get ritase data for these avl_unit, eg: (Rit : 2 rit)
*Ritase are Round trips (about public transportation such as buses, minibuses) in one route
3. HOow can i get information unit is in a area geofencing or not ? eg: (Unit "x" with geofencing "a")
4. It is possible to get KM data from an unit? eg: (KM : 5)
5. I've get report data with this API :
{{url}}svc=report/exec_report&params={"reportResourceId":22326287,"reportTemplateId":1,"reportObjectId":22835406,"reportObjectSecId":0,"interval":{"from":1609434000,"to":1625696065,"flags":0}}&sid={{sid}}

but, the return is :
{
    "reportResult": {
        "msgsRendered": 0,
        "stats": [],
        "tables": [
            {
                "name": "unit_group_events",
                "label": "Payload in geofence",
                "grouping": {
                    "type": "total",
                    "sortColumn": 3,
                    "hide": 1
                },
                "flags": 0,
                "rows": 11,
                "level": 1,
                "columns": 6,
                "header": [
                    "Grouping",
                    "Event time",
                    "Time received",
                    "Event text",
                    "Location",
                    "Notification text"
                ],
                "header_type": [
                    "",
                    "time",
                    "recv_time",
                    "evt_text",
                    "location",
                    "notification_text"
                ]
            }
        ],
        "attachments": []
    }
}
