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

Chilkat.Http http = new Chilkat.Http();

Chilkat.HttpRequest req = new Chilkat.HttpRequest();
req.AddParam("grant_type","password");
req.AddParam("scope","api/ratings api/addin rest");
req.AddParam("username","my_username");
req.AddParam("password","my_password");
// I have no idea of where to get the client_id or client_secret.
// When you create a Moody's App, it only provides an "API Key".
req.AddParam("client_id","my_client_id");
req.AddParam("client_secret","my_client_secret");
