-- 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).

-- To send email, 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.)
--

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

--     {
--       "message": {
--         "subject": "Meet for lunch?",
--         "body": {
--           "contentType": "Text",
--           "content": "The new cafeteria is open."
--         },
--         "toRecipients": [
--           {
--             "emailAddress": {
--           "name": "Chilkat Software",
--               "address": "admin@chilkat.io"
--             }
--           },
--           {
--             "emailAddress": {
--               "address": "chilkat.support@gmail.com"
--             }
--           }
--         ],

--           "name": "Chilkat Blog",
--           "address": "admin@cknotes.com"
--             }

--         ]
