// Specify the URL of the Dropbox API endpoint, the base URL is prepended by default

// Set the HTTP request method to POST
req.setMethod("POST");

// Specify the body and let it be converted to JSON
Map<String, Object> body = new HashMap<String, Object>();
body.put("limit", 100);

// Specify the headers
Map<String, String> headers = new HashMap<String, String>();

// Execute the request, CloudRail will start the authentication flow if necessary
// and append the authorization header.
// The response is checked for errors.
