* 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"

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')

* Add the access (bearer) token to the request, which is a header
* having the following format:
* Authorization: Bearer <userAccessToken>
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbAuth = CreateObject('Chilkat.StringBuilder')
loSbAuth.Append("Bearer ")
loSbAuth.Append(lcAccessToken)
loHttp.SetRequestHeader("Authorization",loSbAuth.GetAsString())

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
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")

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

* The response should be JSON, even if an error.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJson = CreateObject('Chilkat.JsonObject')

* See the sample JSON response below..

* Iterate over the words..
lnNumWords = loJson.SizeOfArray("transcripts.latest.words")
i = 0
DO WHILE i < lnNumWords
