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

' Insert your Bearer token here:

accessToken = "VOICEBASE_TOKEN"

Dim http As Chilkat.Http

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