To obtain data on request you can use the URL

1 To get data for any host items

  https://baozam.net/index.php?action=csv&items=<ITEMID 1>,<ITEMID 2>,<...>,<ITEMID N>&period=<PERIOD_IN_SECONDS>&stime=<START_UNIXTIME>&step=<STEP>

2 To get only pass counters data

  https://baozam.net/index.php?action=csv&hosts=<HOSTID>&period=<PERIOD_IN_SECONDS>&stime=<START_UNIXTIME>&step=<STEP>

Script should pass login and password into POST request for authentication.

HOSTID - it's same id as in url of this device (host). For example https://baozam.net/index.php?obj=host&act=preview&id=10233

ITEMID N - it's same id as in url of device items (host). For example, Events item https://baozam.net/index.php?action=history&items=27714

STIME - unixtime of begin of period. If = 0, then period begin will be calculated as difference between current time and period length.

STEP - seconds count, or predefined values

1. g1h - by hours
2. g1d - by days
3. g1w - by weeks
4. g1m - by monthes

CURL example

HOST=baozam.net
DEVICE=
PERIOD=$(( 7 * 24 * 3600 ))
STIME=0
STEP=g1h
USER=
PWD=

curl "https://$HOST/index.php?action=csv&hosts=$DEVICE&period=$PERIOD&stime=$STIME&step=$STEP" \
    -H "Host: $HOST" --compressed \
    -d "name=$USER" -d "password=$PWD"

VB script

For example:

' This Sub downloads the FILE specified in myUrl to the file specified in mySaveTo.

Const myDevice = "<HOSTID>", myUser = "<USR>", myPwd = "<PASSWORD>"
Const myHost = "baozam.net", mySaveTo = "D:\baozam.csv"
Const myPeriod = "259200", mySTime = "0", myStep = "g1d"

HTTPDownload "https://" + myHost + "/index.php?action=csv&hosts=" + myDevice + "&period=" + myPeriod + "&stime=" + mySTime + "&step=" + myStep
Sub HTTPDownload( myUrl )

    objHTTP.Open "POST", myUrl, False
    'objHTTP.Option(4) = &H3300 'WinHttpRequestOption_SslErrorIgnoreFlags = 0x3300      
    objHTTP.setRequestHeader "myHost", myHost
    objHTTP.SetRequestHeader "Content-Type", "application/x-www-form-urlencoded"
    objHTTP.Send "name=" + myUser + "&password=" + myPwd

    ' Write the downloaded byte stream to the target file
    For i = 1 To LenB( objHTTP.ResponseBody )
        objFile.Write Chr( AscB( MidB( objHTTP.ResponseBody, i, 1 ) ) )
    Next
