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

loHttp = CreateObject('Chilkat.Http')

* 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).

loHttp.AuthToken = "MICROSOFT_GRAPH_ACCESS_TOKEN"

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

* Build the HTML body...
lnBCrlf = 1
loSbHtmlBody = CreateObject('Chilkat.StringBuilder')
loSbHtmlBody.AppendLine("<html>",lnBCrlf)
loSbHtmlBody.AppendLine("<head>",lnBCrlf)
loSbHtmlBody.AppendLine('<meta http-equiv="Content-Type" content="text/html; charset=utf-8">',lnBCrlf)
loSbHtmlBody.AppendLine('<meta content="text/html; charset=utf-8">',lnBCrlf)
loSbHtmlBody.AppendLine("</head>",lnBCrlf)
loSbHtmlBody.AppendLine('<body bgcolor="#FFFFFF">',lnBCrlf)
loSbHtmlBody.AppendLine('<font face="Calibri">This is a test <b>HTML email</b>.<br>',lnBCrlf)
loSbHtmlBody.AppendLine("</font>",lnBCrlf)
loSbHtmlBody.AppendLine("</body>",lnBCrlf)
loSbHtmlBody.AppendLine("</html>",lnBCrlf)

* The body of the POST request contains JSON that specifies the email subject, body,
* recipients, etc.  This example will build the following JSON HTML email:
* 

* 	{
* 	  "message": {
* 	    "subject": "Sample HTML Email",
* 	    "body": {
* 	      "contentType": "html",
* 	      "content": "The HTML body goes here..."
* 	    },
* 	    "toRecipients": [
* 	      {
* 	        "emailAddress": {
* 		  "name": "Chilkat Software",
* 	          "address": "admin@chilkat.io"
* 	        }
* 	      },
* 	      {
* 	        "emailAddress": {
* 	          "address": "chilkat.support@gmail.com"
* 	        }
* 	      }
* 	    ],
* 	    "ccRecipients": [
* 	      {
* 	        "emailAddress": {
* 		  "name": "Chilkat Blog",
* 		  "address": "admin@cknotes.com"
* 	        }
* 	      }
* 	    ]
* 	  },
* 	  "saveToSentItems": true
* 	}
* 

* Build the above JSON.

loJson.UpdateString("message.subject","Sample HTML email")
loJson.UpdateString("message.body.contentType","html")

    RELEASE loSbHtmlBody

* The send succeeded if the response status code = 202.
* In the success case, there is no response body.  (We just get the response code to know that it succeeded.)
