Lua

local chilkat = require("chilkat")

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

local http = chilkat.Http.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).

http.auth_token = "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...
local bCrlf = true
local sbHtmlBody = chilkat.StringBuilder.new()
sbHtmlBody:append_line("<html>", bCrlf)
sbHtmlBody:append_line("<head>", bCrlf)
sbHtmlBody:append_line("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\">", bCrlf)
sbHtmlBody:append_line("<meta content=\"text/html; charset=utf-8\">", bCrlf)
sbHtmlBody:append_line("</head>", bCrlf)
sbHtmlBody:append_line("<body bgcolor=\"#FFFFFF\">", bCrlf)
sbHtmlBody:append_line("<font face=\"Calibri\">This is a test <b>HTML email</b>.<br>", bCrlf)
sbHtmlBody:append_line("</font>", bCrlf)
sbHtmlBody:append_line("</body>", bCrlf)
sbHtmlBody:append_line("</html>", bCrlf)

-- 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",
