'  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 ChilkatHttp
http.Initialize("http")

Dim req As ChilkatHttpRequest

'  having the following format:
'  Authorization: Bearer <userAccessToken>
Dim sbAuth As ChilkatStringBuilder
sbAuth.Initialize
sbAuth.Append("Bearer ")
sbAuth.Append(accessToken)
req.AddHeader("Authorization", sbAuth.GetAsString)
