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

// First get our previously obtained OAuth2 access token.

// --------------------------------------------------------------------------
// Note: The above code to setup the initial REST connection
// can be done once.  After connecting, any number of REST calls can be made.
// If the connection is lost, the next REST method call will automatically
// reconnect if needed.
// --------------------------------------------------------------------------

// Technically, the POST has an empty request body, but the Quickbooks documentation indicates that 
// the Content-Type header should be set to "application/octet-stream", which really makes no sense
// because there is not content. (How can no content have a type???)
