ActiveX for 32-bit and 64-bit Windows

' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim success As Long

Dim http As New ChilkatHttp
http.AuthToken = "GMAIL-ACCESS-TOKEN"

Dim userId As String
userId = "me"
success = http.SetUrlVar("userId",userId)

Dim url As String
url = "https://www.googleapis.com/gmail/v1/users/{$userId}/labels"

' Get the list of GMail labels as JSON.
Dim sb As New ChilkatStringBuilder
success = http.QuickGetSb(url,sb)
If (success <> 1) Then
    Debug.Print http.LastErrorText
    Exit Sub
End If

Dim json As New ChilkatJsonObject
success = json.LoadSb(sb)
json.EmitCompact = 0
Debug.Print json.Emit()

If (http.LastStatus <> 200) Then
    Debug.Print "Failed."
    Exit Sub
End If

' 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"
'     },
'     {
'       "id": "CATEGORY_PERSONAL",
'       "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...
Dim jRecord As ChilkatJsonObject
Set jRecord = json.FindRecord("labels","name","QA",0)
If (json.LastMethodSuccess = 1) Then
    Debug.Print "The id of QA is: " & jRecord.StringOf("id")

End If

Set jRecord = json.FindRecord("labels","name","[Gmail]/testFolder",0)
If (json.LastMethodSuccess = 1) Then
    Debug.Print "The id of [Gmail]/testFolder is: " & jRecord.StringOf("id")

End If

Set jRecord = json.FindRecord("labels","name","questions",0)
If (json.LastMethodSuccess = 1) Then
    Debug.Print "The id of questions is: " & jRecord.StringOf("id")

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
