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

// Insert your Bearer token here:
Dim accessToken As String
accessToken = "VOICEBASE_TOKEN"

Dim http As New Chilkat.Http

Dim req As New Chilkat.HttpRequest
req.HttpVerb = "POST"
req.Path = "/v2-beta/media"

// Add the access (bearer) token to the request, which is a header
// having the following format:
// Authorization: Bearer <userAccessToken>
Dim sbAuth As New Chilkat.StringBuilder
success = sbAuth.Append("Bearer ")
success = sbAuth.Append(accessToken)
req.AddHeader "Authorization",sbAuth.GetAsString()

Dim success As Boolean
success = req.AddFileForUpload2("media","qa_data/wav/msg_123_abc.wav","audio/x-wav")

// Examine the response status code and body.
System.DebugLog("Response status code = " + Str(resp.StatusCode))

// The response should be JSON, even if an error.
