// See Global Unlock Sample for sample code.

http := TChilkatHttp.Create(Self);

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

// 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

// This example will delete the file named "penguins2.jpg" 
// which is located in the "/Documents" folder.

req.HttpVerb := 'POST';
req.Path := '/_api/web/GetFileByServerRelativeUrl(''/Documents/penguins2.jpg'')';

// We need to add a form digest value in the X-RequestDigest header field.
// See this example for details on
// how to get (and cache) a form digest value
req.AddHeader('X-RequestDigest','SHAREPOINT_FORM_DIGEST');

// Add additional required headers.
req.AddHeader('IF-MATCH','*');
req.AddHeader('X-HTTP-Method','DELETE');

// Send the POST using https (TLS). Port 443 is the default port for https.

// If failed, the response body contains XML

  begin
    Memo1.Lines.Add('Response status code = ' + IntToStr(resp.StatusCode));
    Memo1.Lines.Add(xml.GetXml());

    // For example, if the file did not exist, this would be the XML response:
    // <?xml version="1.0" encoding="utf-8" ?>
    // <m:error xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
    //     <m:code>-2146232832, Microsoft.SharePoint.SPException</m:code>
