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

' Search for media containing the terms any of the terms "test", "number", or "three"
