VoiceBase -- Upload a media file for transcription and analysis

See more VoiceBase Examples

This example demonstrates how to upload a media file for transcription and analysis. It duplicates the following curl command:

curl https://apis.voicebase.com/v2-beta/media \
  --form media=@msg_123_abc.wav \
  --header "Authorization: Bearer ${TOKEN}"

VB.NET

Dim success As Boolean = False

' 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 = "VOICEBASE_TOKEN"

Dim http As New Chilkat.Http

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

' 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
sbAuth.Append("Bearer ")
sbAuth.Append(accessToken)
req.AddHeader("Authorization",sbAuth.GetAsString())

success = req.AddFileForUpload2("media","qa_data/wav/msg_123_abc.wav","audio/x-wav")
If (success = False) Then
    Debug.WriteLine(req.LastErrorText)
    Exit Sub
End If


Dim resp As New Chilkat.HttpResponse
success = http.HttpSReq("apis.voicebase.com",443,True,req,resp)
If (success = False) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


' Examine the response status code and body.
Debug.WriteLine("Response status code = " & resp.StatusCode)

' The response should be JSON, even if an error.
Dim json As New Chilkat.JsonObject
json.Load(resp.BodyStr)
json.EmitCompact = False

Debug.WriteLine(json.Emit())

' A successful response will have a status code = 200
If (resp.StatusCode <> 200) Then
    Debug.WriteLine("Failed.")
Else
    Debug.WriteLine("mediaId: " & json.StringOf("mediaId"))
    Debug.WriteLine("href: " & json.StringOf("_links.self.href"))
    Debug.WriteLine("status: " & json.StringOf("status"))
    Debug.WriteLine("Success.")
End If


' Here is an example of a successful response:

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