' 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 = http.QuickGetStr(sbUrl.GetAsString())
If (http.LastMethodSuccess <> True) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub

' The response should be JSON, even if an error.
Dim json As New Chilkat.JsonObject
