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

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

// If SharePoint Windows classic authentication is used, then set the 
// Login, Password, LoginDomain, and NtlmAuth properties.
http.Login = "SHAREPOINT_USERNAME";
http.Password = "SHAREPOINT_PASSWORD";
http.LoginDomain = "SHAREPOINT_NTLM_DOMAIN";
http.NtlmAuth = true;

// The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
// If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
// establish the cookie as shown at SharePoint Online Authentication

// To create a list, we're going to POST to
// https://SHAREPOINT_HTTPS_DOMAIN/_api/web/lists
// with a request body containing the following JSON:
// 
// {
//   "__metadata": {
//     "type": "SP.List"
//   },
//   "AllowContentTypes": true,
//   "BaseTemplate": 100,
//  "ContentTypesEnabled": true,
//  "Description": "My list description",
//  "Title": "Test"
// }

// This example will create a folder named ChilkatTest in /Documents

// how to get (and cache) a form digest value

// Set the Content-Type, and indicate that a JSON response is desired.
