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

let http = chilkat::Http::new();

// Use your actual access token instead of 555555555555555555555555555555
let req = chilkat::HttpRequest::new();

// Note: The WaTrend online documentation indicate a POST should be used.
// However, it seems you might actually need to send a GET request.
// It is unclear.  
// If a GET is neeed, you would just send to the URL w/ query params like this:

// The responseBodyStr contains the JSON response from the server..

// Both success and failed responses use 200 status code.

// A success response contains this JSON in the response body:
// {"status":"success", ... }

// A failed response will contain something like this:
// {"status":"error","message":"License Invalidated"}
