*  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 = "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>
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 = 0) THEN
    ? loReq.LastErrorText
    RELEASE loHttp
    RELEASE loReq
    RELEASE loSbAuth
    CANCEL
ENDIF

*  This is the JSON of the configuration to be added as a parameter to the upload:
*  (Obviously, if you want a callback, you would use a URL that goes to your own web server..)

*  	{ 
*  	   "configuration":{ 
*  	      "publish":{ 
*  	         "callbacks":[
*  	            { 
*  	               "url":"https://www.chilkatsoft.com/dss/update_vm_transcription.asp",
*  	               "method":"POST",
*  	               "include":[
*  	                  "transcripts",
*  	                  "keywords",
*  	                  "topics",
*  	                  "metadata"
*  	               ]
*  	            }
*  	         ]

*  	      "keywords":{ 
*  	         "groups":[]
*  	      }
*  	   }
*  	}

*  This code produces the above JSON.
