'  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 ChilkatHttp
http.Initialize("http")

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

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

Dim strJson As String = http.QuickGetStr(sbUrl.GetAsString)
If http.LastMethodSuccess <> True Then
    Log(http.LastErrorText)
    Return
End If


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

Log("Response status code = " & http.LastStatus)

If http.LastStatus <> 200 Then
    Log(json.Emit)
    Log("Failed")
    Return
End If


'  See the sample JSON response below..

'  Iterate over the words..
Dim numWords As Int = json.SizeOfArray("transcripts.latest.words")
Dim i As Int = 0
Do While i < numWords
    json.I = i
    Log(json.StringOf("transcripts.latest.words[i].w"))
    i = i + 1
Loop
Log("Success.")
