* 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')

loReq = CreateObject('Chilkat.HttpRequest')
loReq.HttpVerb = "GET"
loReq.Path = "/v2-beta/media"

* 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)
loReq.AddHeader("Authorization",loSbAuth.GetAsString())

* Search for media containing the terms any of the terms "test", "number", or "three"
loReq.AddParam("query",'"test" OR "number" OR "three"')

loResp = CreateObject('Chilkat.HttpResponse')
lnSuccess = loHttp.HttpSReq("apis.voicebase.com",443,1,loReq,loResp)
IF (lnSuccess = 0) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loReq
    RELEASE loSbAuth
    RELEASE loResp
    CANCEL
ENDIF

* Examine the response status code and body.
? "Response status code = " + STR(loResp.StatusCode)

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

* A successful response will have a status code = 200
IF (loResp.StatusCode <> 200) THEN
    ? "Failed."
ELSE
    ? "mediaId: " + loJson.StringOf("mediaId")
    ? "href: " + loJson.StringOf("_links.self.href")
    ? "status: " + loJson.StringOf("status")
    ? "Success."
ENDIF

* See the sample JSON response below..

* Iterate over the JSON like this:
loDt = CreateObject('Chilkat.CkDateTime')
loDtObj = CreateObject('Chilkat.DtObj')

lnMediaCount = loJson.SizeOfArray("media")
i = 0
DO WHILE i < lnMediaCount
    loJson.I = i

    ? "-- " + STR(i) + " --"
    ? "  mediaId: " + loJson.StringOf("media[i].mediaId")
    ? "  status: " + loJson.StringOf("media[i].status")
    ? "  contentType: " + loJson.StringOf("media[i].metadata.contentType")
    ? "  milliseconds: " + loJson.StringOf("media[i].metadata.length.milliseconds")
    ? "  descriptive: " + loJson.StringOf("media[i].metadata.length.descriptive")
    lcDateCreated = loJson.StringOf("media[i].dateCreated")
    loDt.SetFromTimestamp(lcDateCreated)

    lnLocalTime = 1
    loDt.ToDtObj(lnLocalTime,loDtObj)

    ? "  " + STR(loDtObj.Month) + "/" + STR(loDtObj.Day) + "  " + STR(loDtObj.Hour) + ":" + STR(loDtObj.Minute)

    i = i + 1
