Going out on a limb here, since you didn't deem it necessary to include the actual error message. You're most likely getting an "invalid character" error in line 3. That's because you need to define your JSON string as an actual string.

Change this:

strJSONToSend = {"type": "note", "title": "Alert", "body": "Lorem Ipsum Lorem Ipsum Lorem Ipsum."}

into this:

strJSONToSend = "{""type"": ""note"", ""title"": ""Alert"", ""body"": ""Lorem Ipsum Lorem Ipsum Lorem Ipsum.""}"

Edit: As a side-note, if you're using On Error Resume Next in your code always put proper error handling in place, and also keep it as localized as possible:

On Error Resume Next   'enable error handling
objXmlHttpMain.open "POST",URL, False
If Err Then            'handle errors
  WScript.Echo Err.Description & " [0x" & Hex(Err.Number) & "]"
  WScript.Quit 1
End If
On Error Goto 0        'disable error handling again
