Did you try Device telemetry API ?

You can send get/ post request to get telemetry details of the devices. The API will return geo location of the device.

The usage of API is provided at this location on GitHub .

Sample Get Request:

GET {Device Telemetry endpoint}/messages?from={time}&to={time}&order=desc&grouplimit=1&devices=id1,id2,id3,...

Sample Post Request:

POST {Device Telemetry endpoint}/messages-query
Content-Type: application/json; charset=utf-8

{
    From: {time}
    To: {time}
    Order: desc
    GroupLimit: 1
    Devices: [ id1, id2, id3, ... ]
}

Sample Response:

Content-Type: application/json; charset=utf-8

{
    Items: [
        {
            deviceid
            time
            value 1
            value 2
            value N
            $metadata
        },
        {
            deviceid
            time
            value 1
            value 2
            value N
            $metadata
        },
        ...
    ],
    "$metadata": {
        $type: MessagesList;1
        $uri: ...
    }
}

Hope this helps.
