This example uploads a media file and also provides a configuration file.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows

' 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 ChilkatHttp

Dim req As New ChilkatHttpRequest
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 ChilkatStringBuilder
success = sbAuth.Append("Bearer ")
success = sbAuth.Append(accessToken)
req.AddHeader "Authorization",sbAuth.GetAsString()

Dim success As Long
success = req.AddFileForUpload2("media","qa_data/wav/msg_123_abc.wav","audio/x-wav")
If (success <> 1) Then
    Debug.Print req.LastErrorText
    Exit Sub
End If

' 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..)
