Yahoo Mail Send using OAuth2 Access Token

See more Yahoo Mail Examples

Demonstrates how to send email using Yahoo and OAuth2 authentication. This example assumes an OAuth2 access token was previously obtained. Lua

local chilkat = require("chilkat")

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

-- See Get Yahoo Mail OAuth2 Access Token for Desktop App
-- for sample code showing how to obtain a Yahoo Mail access token.

-- In this example, our access token was previously saved to the following file which contains JSON like this:
-- {
--   "access_token": "kCVQdnOdul...LHucA--",
--   "refresh_token": "AIenVXETSo0jklFBVkPS8vVm8E.Ej9ToRG.xDbDYmZ65WIs5t6CZhDrD",
--   "expires_in": 3600,
--   "token_type": "bearer",
--   "xoauth_yahoo_guid": "HGDQCVF5JB4YDOWHITQJFBHCWA"
-- }

local json = chilkat.JsonObject.new()
local success = json:load_file("qa_data/tokens/yahooMail.json")
if not success then
    print("Failed to load Yahoo access token file.")
    return
end

local accessToken = json:string_of("access_token")

local mailman = chilkat.MailMan.new()

-- Set the properties for the Yahoo SMTP server:
mailman.smtp_host = "smtp.mail.yahoo.com"
mailman.smtp_port = 465
mailman.smtp_ssl = true

-- The SMTP username should be the Yahoo email address of the user's account that authorized your app to send email.
mailman.smtp_username = "user@yahoo.com"
mailman.oauth2_access_token = accessToken

-- Create a new email object
local email = chilkat.Email.new()

email.subject = "This is a test"
email.body = "This is a test"
email.from = "Joe User <user@yahoo.com>"
email:add_to("Chilkat Admin", "admin@chilkatsoft.com")
-- To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

-- Call SendEmail to connect to the SMTP server and send.
-- The connection (i.e. session) to the SMTP server remains
-- open so that subsequent SendEmail calls may use the
-- same connection.
success = mailman:send_email(email)
if not success then
    print(mailman.last_error_text)
    return
end

-- You may close the connection here.  If the connection is kept open,
-- the next call to mailman.SendEmail will continue using the already-established connection
-- (and automatically re-connect if needed).
success = mailman:close_smtp_connection()
if not success then
    print("Connection to SMTP server not closed cleanly.")
end

print("Email Sent via Yahoo with OAuth2 authentication.")
