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

// Note: Define your Twitter apps at https://apps.twitter.com/

// We're going to send an HTTPS POST that looks like this:

// POST /oauth2/token HTTP/1.1
// Host: api.twitter.com
// User-Agent: My Twitter App v1.0.23
// Authorization: Basic eHZ6MWV2RlM0d0VFUFRHRUZQSEJvZzpMOHFxOVBaeVJn

// Content-Type: application/x-www-form-urlencoded;charset=UTF-8
// Content-Length: 29
// Accept-Encoding: gzip
// 
// grant_type=client_credentials

// Update these values with your consumer key and secret (also known as API key and API secret).
