VBA download a File from OneDrive

I am trying to download a file from OneDrive. I am new to API Concepts and here is Code,

Sub OneDrive_Download()

'Declare the Object
Dim oRequest As Object

'Create and Assign Object
Set oRequest = CreateObject("MSXML2.XMLHTTP")

'Input User OneDrive URL
URL = "https://xxxx-my.sharepoint.com/personal/sidxxx_ie/"

'Post the URL in the Object
oRequest.Open "POST", URL, False

'Send Keys to the API
oRequest.send ("{""client_id"":myclientid,""CLIENT_SECRET"":myclientsecret}")


'Print the Response in the Immediate Window
 Debug.Print oRequest.ResponseText

 End Sub

And this is the Response that I got from Debug.Print on my Immediate window,

// Setup cta message fields.
window.$Do.when("User", 0, function ()
{
    User.setupCallToActionMessages();
});

// Other tile
var Tiles = Tiles || {};
Tiles.otherJSON = {
    'name': 'Use another account',
    'login': '',
    'imageAAD': 'other_glyph.png',
    'imageMSA': 'other_glyph.png',
    'isLive': false,
    'link': 'other',
    'authUrl': '',
    'sessionID': '',
    'domainHint': 'other'
};
</script>
</body>
</html>

Now I am looking to download a file named as test.xlsx in my OneDrive. What is the way to go about it.

UPDATED - CODE

Sub DownloadFile()

'Declare the Object and URL
Dim myURL As String
Dim WinHttpReq As Object

'Assign the URL and Object to Variables
myURL = "https://xxx-my.sharepoint.com/personal/Sidxxx/Documents/test.xlsx"
Set WinHttpReq = CreateObject("Microsoft.XMLHTTP")

'Provide Access Token and PWD to the URL for getting the service from API
WinHttpReq.Open "GET", myURL, False, "abcdef", "12345"
WinHttpReq.send

Debug.Print WinHttpReq.Status

myURL = WinHttpReq.responseBody

    If WinHttpReq.Status = 200 Then

        Set oStream = CreateObject("ADODB.Stream")

        oStream.Open

        oStream.Type = 1

        oStream.SaveToFile "C:\testdownload.xlsx", 2

        oStream.Close

    End If

End Sub

The file is now getting downloaded. But it appears to be empty.

This code works for me. Thanks everyone for your advice.

Debug.Print WinHttpReq.Status

        Set oStream = CreateObject("ADODB.Stream")

        oStream.Open

        oStream.Type = 1

         oStream.Write WinHttpReq.responseBody

        oStream.SaveToFile "C:\testdownload.xlsx", 2

        oStream.Close

    End If

End Sub
