'  This requires the Chilkat API to have been previously unlocked.

'  -------------------------------------------------------------------------
'  The following comments apply to SharePoint Windows classic authentication.
'  -------------------------------------------------------------------------
'  For example, imagine our SharePoint endpoint is https://xyzoffice.mycompany.com/
'  The SHAREPOINT_NTLM_DOMAIN would be "mycompany.com"
'  The SHAREPOINT_HTTPS_DOMAIN would be "xyzoffice.mycompany.com"
'  Also, the SHAREPOINT_USERNAME would be just the name, not a full email address.
'  for example, "chilkat" instead of "chilkat@mycompany.com"

Dim http As Chilkat.Http
Set http = Chilkat.NewHttp

'  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
'  -------------------------------------------------------------------------

'  When creating, updating, and deleting SharePoint entities, we'll need
'  to first get the server's form digest value to send in the X-RequestDigest header.
'  This can be retrieved by making a POST request with an empty body to
'  http://<site url>/_api/contextinfo and extracting the value of the
'  d:FormDigestValue node in the XML that the contextinfo endpoint returns.

Set resp = http.PostXml("https://SHAREPOINT_HTTPS_DOMAIN/_api/contextinfo","","utf-8")
