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

Dim http As New Chilkat.Http

// Build and send the following JSON:

// The "retref" is the value returned in the JSON response for the Authorization request.

// {
//     "retref":"112989260941",
//     "merchid":"MERCHANT_ID"
// }

// A response status of 200 indicates potential success.  The JSON response body
