'  The JSON returned looks like this:
'  {
'    "labels": [
'      {
'        "id": "Label_5",
'        "name": "QA",
'        "messageListVisibility": "show",
'        "labelListVisibility": "labelShow",
'        "type": "user"
'      },
'      {
'        "id": "Label_21",
'        "name": "[Gmail]/testFolder",
'        "type": "user"
'      },
'      {

'        "name": "CATEGORY_PERSONAL",
'        "type": "system"
'      },
'  	...

'  The name of the label is generally known because it's what we visually see.
'  The id is what we need to get.  Assuming the name is unique,
'  find the JSON record having name=<desired name>
'  For example...
' jRecord is a Chilkat.JsonObject
Set jRecord = json.FindRecord("labels","name","QA",0)
If (json.LastMethodSuccess = 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( "The id of QA is: " & jRecord.StringOf("id")) & "</pre>"

End If

' jRecord is a Chilkat.JsonObject
Set jRecord = json.FindRecord("labels","name","[Gmail]/testFolder",0)
If (json.LastMethodSuccess = 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( "The id of [Gmail]/testFolder is: " & jRecord.StringOf("id")) & "</pre>"

End If

' jRecord is a Chilkat.JsonObject
Set jRecord = json.FindRecord("labels","name","questions",0)
If (json.LastMethodSuccess = 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( "The id of questions is: " & jRecord.StringOf("id")) & "</pre>"

End If

'  Output:

'  The id of QA is: Label_5
'  The id of [Gmail]/testFolder is: Label_21
'  The id of questions is: Label_43
