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

$http = chilkat::CkHttp->new();

#  Use your previously obtained access token here:
#  See the following examples for getting an access token:
#     Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint).
#     Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint).
#     Refresh Access Token (Azure AD v2.0 Endpoint).
#     Refresh Access Token (Azure AD Endpoint).

#  To send mail, we'll POST to the following endpoint:
#  
#  POST /users/{id | userPrincipalName}/sendMail
#  
#  (The special keyword "me" may be used in place of a principal name.)
#  

#  This example will send HTML email containing the following HTML body:

#  	<html>
#  	<head>
#  	<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
#  	<meta content="text/html; charset=utf-8">

#  	<body bgcolor="#FFFFFF">
#  	<font face="Calibri">This is a test <b>HTML email</b>.<br>

#  	</body>
#  	</html>

#  Build the HTML body...
