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

' Insert your Bearer token here:
Dim accessToken As String = "VOICEBASE_TOKEN"

Dim http As New Chilkat.Http

' Add the access (bearer) token to the request, which is a header
' having the following format:
' Authorization: Bearer <userAccessToken>
Dim sbAuth As New Chilkat.StringBuilder
sbAuth.Append("Bearer ")
sbAuth.Append(accessToken)
http.SetRequestHeader("Authorization",sbAuth.GetAsString())

Dim sbUrl As New Chilkat.StringBuilder
sbUrl.Append("https://apis.voicebase.com/v2-beta/media/$MEDIA_ID/transcripts/latest")
Dim replaceCount As Integer = sbUrl.Replace("$MEDIA_ID","f9b9bb88-d52c-4960-bcef-d516a9f85594")

Dim strJson As String = Await http.QuickGetStrAsync(sbUrl.GetAsString())
If (http.LastMethodSuccess <> True) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


' The response should be JSON, even if an error.
Dim json As New Chilkat.JsonObject
json.Load(strJson)
json.EmitCompact = False

Debug.WriteLine("Response status code = " & http.LastStatus)

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


' See the sample JSON response below..

' Iterate over the words..
Dim numWords As Integer = json.SizeOfArray("transcripts.latest.words")
Dim i As Integer = 0
While i < numWords
    json.I = i
    Debug.WriteLine(json.StringOf("transcripts.latest.words[i].w"))
    i = i + 1
