' Note: Requires Chilkat v9.5.0.64 or greater.

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

Dim rest As New ChilkatRest
Dim success As Long

' Before sending REST API calls, the REST object needs to be
' initialized for OAuth1.
' See Xero 2-Legged OAuth1 Setup for sample code.

' Assuming the REST object's OAuth1 authenticator is setup, and the initial
' connection was made, we may now send REST HTTP requests..
