  --form media=@msg_123_abc.wav \
  --header "Authorization: Bearer ${TOKEN}"

* 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')

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.HttpRequest')
loReq = CreateObject('Chilkat.HttpRequest')
loReq.HttpVerb = "POST"
loReq.Path = "/v2-beta/media"
loReq.ContentType = "multipart/form-data"

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

lnSuccess = loReq.AddFileForUpload2("media","qa_data/wav/msg_123_abc.wav","audio/x-wav")
IF (lnSuccess <> 1) THEN
    ? loReq.LastErrorText
    RELEASE loHttp
    RELEASE loReq
    RELEASE loSbAuth
    CANCEL
ENDIF

loResp = loHttp.SynchronousRequest("apis.voicebase.com",443,1,loReq)
IF (loHttp.LastMethodSuccess <> 1) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loReq
    RELEASE loSbAuth
    CANCEL
ENDIF

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

* 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')
loJson.Load(loResp.BodyStr)
loJson.EmitCompact = 0

? loJson.Emit()

* 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

RELEASE loResp

* Here is an example of a successful response:

* 	{ 
* 	  "_links": { 
* 	    "self": { 
* 	      "href": "/v2-beta/media/856a1e85-c847-4c3c-b7a4-6cf15cd51db4"
