Replace name/filename as needed, set ctype to text/csv and finally replace /sendPhoto with /sendDocument in the URL.

Code:

filedata = table.concat(buffer, '\n')

1. Install Telegram app

2. Find BotFather or go here https://t.me/botfather

3. Once in BotFather type /newbot and follow instructions. As a result you will get your token and your own bot link like t.me/yourname_bot Click on the link and type any message there

4. Open browser (preferably Firefox as it converts JSON automatically) and go here https://api.telegram.org/bot<token>/getUpdates. Replace <token> with your token. As a result you should have something like that. Save your chat ID


5. Create a user library called telegram. paste this code and replace your token and chat ID

Code:

require('ssl.https')

local token = 'token' -- your token
local chat_id = '1234567' -- your chat id

function telegram(message)
  local url = 'https://api.telegram.org/bot' .. token .. '/sendMessage'
  local data = 'chat_id=' .. chat_id .. '&text=' .. socket.url.escape(message)
  return ssl.https.request(url, data)
end

6. Create an event based script and use this code to send message to Telegram app:

Code:

require("user.telegram")
message = 'test message'
res, err = telegram(message)
log(res, err)

For older fw it will work like this

    method = 'GET',
    url = url,
    protocol = 'tlsv12',

local chat_id = '12345'
local token = 'wwwwwwwwwwwwwwwwwwwwwwwwww'
local telegram_url = 'https://api.telegram.org/bot' .. token .. '/sendMessage?'


message = "test"
message=require('socket.url').escape(message)
data_str = 'chat_id=' .. chat_id .. '&text=' .. message..''
stat, code, hdrs = request(telegram_url .. data_str)

Hello, Daniel!
I have LM2 upgraded to 20181002 version.
I used your code for older fw.
