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

*  Insert your Bearer token here:
lcAccessToken = "VOICEBASE_TOKEN"

loHttp = CreateObject('Chilkat.Http')

*  Add the access (bearer) token to the request, which is a header
*  having the following format:
*  Authorization: Bearer <userAccessToken>
loSbAuth = CreateObject('Chilkat.StringBuilder')
loSbAuth.Append("Bearer ")
loSbAuth.Append(lcAccessToken)
loHttp.SetRequestHeader("Authorization",loSbAuth.GetAsString())

loSbUrl = CreateObject('Chilkat.StringBuilder')
loSbUrl.Append("https://apis.voicebase.com/v2-beta/media/$MEDIA_ID/transcripts/latest")
lnReplaceCount = loSbUrl.Replace("$MEDIA_ID","f9b9bb88-d52c-4960-bcef-d516a9f85594")

lcStrJson = loHttp.QuickGetStr(loSbUrl.GetAsString())
IF (loHttp.LastMethodSuccess <> 1) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loSbAuth
    RELEASE loSbUrl
    CANCEL
ENDIF

*  The response should be JSON, even if an error.
loJson = CreateObject('Chilkat.JsonObject')
loJson.Load(lcStrJson)
loJson.EmitCompact = 0

? "Response status code = " + STR(loHttp.LastStatus)

IF (loHttp.LastStatus <> 200) THEN
    ? loJson.Emit()
    ? "Failed"
    RELEASE loHttp
    RELEASE loSbAuth
    RELEASE loSbUrl
    RELEASE loJson
    CANCEL
ENDIF

*  See the sample JSON response below..

*  Iterate over the words..
lnNumWords = loJson.SizeOfArray("transcripts.latest.words")
i = 0
DO WHILE i < lnNumWords
    loJson.I = i
    ? loJson.StringOf("transcripts.latest.words[i].w")
    i = i + 1
ENDDO
? "Success."
