Telegram might be a new name to you, but it’s gaining popularity the in the last few years, in recent news Telegram reported 100,000,000 monthly active users. So what is it all about ?

Telegram is a cloud based messaging app which is well known for a variety of features and it’s secure messaging being one of key features. It supports a variety of platforms like Windows, OSX, GNU/Linux, Android, iOS and Windows Phone. It is also worth mentioning that the client side of Telegram is open source, so we cold be using any other messaging app like Pidgin to connect with Telegram.

Some of the features of Telegram:

  • Encryption
  • Super Groups (1000 members or more)
  • File/Photos transfer
  • Open source client side
  • Synchronizes your messages through all your devices
  • File size sharing limit 1.5 GB
  • Bots

We are going to talk about the last one in particular. Telegram offers two APIs: The developer API and the bot API

First, we need to sign up for an account. Either download one of the clients or go directly to the web version of Telegram. From there, you’ll be asked to give a phone number and Telegram will send a confirmation SMS.


Meet The BotFather

The BotFather

Bots are special Telegram accounts designed to handle messages automatically. Users can interact with bots by sending them commands in private or group chats. We control our bots using HTTPS requests to the bot API.

What can we do with bots ?

  • Take notes in Telegram groups
  • Get weather updates
  • Play Games
  • Interact with other services such as social networks, IRC, etc.

We can do a lot of stuff with bots. The first step in creating our bot is to talk to the BotFather.

Type in the search form BotFather.


Click on the BotFather and a chat container will be opened so we can chat with him. Hit the start button which will display a list of commands that we can use to interact with the BotFather.


Let’s create our bot using the command /newbot. It is going to ask for a name for our bot, so we’ll call our bot sitepbot.

Now we have to register for a username, note: it must end in bot, If our bot is named TetrisBot the username must be tetrisbot. Let it be sitepointbot.

BotFather will congratulate us, and give a link to our bot

We can add a description and also add a profile picture to our bot. The /help command will give us a list of commands we can interact with BotFather.

/newbot - create a new bot
/token - generate authorization token
/revoke - revoke bot access token
/setname - change a bot's name
/setdescription - change bot description
/setabouttext - change bot about info
/setuserpic - change bot profile photo
/setinline - change inline settings
/setinlinefeedback - change inline feedback settings
/setcommands - change bot commands list
/setjoingroups - can your bot be added to groups?
/setprivacy - what messages does your bot see in groups?
/deletebot - delete a bot
/cancel - cancel the current operation

Using one of the commands above, we can make various changes to our bot. But, right now, the most important command is /token, as it will give us an API token to access our bot through HTTPS. Go ahead and type that now:


The return value will look something like this: 197372558:AAEtvechentOstoPmVyb1_aF2Dbe7k

After creating our bot and having it listen to us, it’s time for some Ruby power. There are several gems to interact with the bot API. We will be using telegram-bot-ruby.


We can install it directly from your terminal:

gem install telegram-bot-ruby

Or add it to our Gemfile:

gem 'telegram-bot-ruby'

If we are using it with the Gemfile we need to enter bundle install in our project directory. This will install the gem and the dependencies it needs.

Hello SitePoint Example

Create a file named sitepointbot.rb, we’ll build out the content of this file here.

First, we need to import our gem:

require 'telegram/bot'

Next, we need to add our token, which we generated earlier:

token = 'YOUR API TOKEN'

Using the bot.api object, we can use all the methods from Bot API: do |bot|
  bot.listen do |message|
    case message.text
    when '/sitepoint'
      bot.api.send_message(chat_id:, text: "Welcome to")

send_message is one of the methods from the Bot API and it sends a message to the current chat_id. chat_id is the unique identifier for the target chat, or user name of the target channel. Of course, text is message to be sent to the chat. Whenever the bot sees /sitepoint in our chat message, it will respond with the “Welcome to!”

Note: It is strongly suggested that we use a slash (/) before our commands, we don’t want our bots to interfere with our conversations.

Complete Code

require 'telegram/bot'

token = 'YOUR API TOKEN' do |bot|
  bot.listen do |message|
    case message.text
    when '/sitepoint'
      bot.api.send_message(chat_id:, text: "Welcome to")

Now it is time to run our bot:

ruby sitepointbot.rb

We have to search for the bot. It will appear in the search result area.


As you can see, there is a “Start” button. If we click the button a /start command will execute. This should always contain a welcome message from our bot, it is the best place to add general information about the bot, like what it does and what commands it understands.


This is the effect of the Start button or the /start command. If you wanted to start the bot inside a chat, you can also type


which is necessary if you have more than one bot in a chat.

Now let’s try /sitepoint.


The result is a welcome message with a link to SitePoint’s website.

One More Example

Let’s use the sendLocation method. This method will make a point on the map. We will be using the same object bot.api, but this time we want the send_location method:

bot.api.send_location(chat_id:, latitude: -37.807416, longitude: 144.985339)

Complete Code

require 'telegram/bot'

token = 'YOUR API KEY' do |bot|
  bot.listen do |message|
    case message.text
    when '/start'
      bot.api.send_message(chat_id:, text: "I am the SitePoint bot, My commands are /sitepoint /map")
    when '/sitepoint'
      bot.api.send_message(chat_id:, text: "Welcome to")
    when '/map'
      bot.api.send_location(chat_id:, latitude: -37.807416, longitude: 144.985339)

Note: We need to exit the bot and start again before seeing the changes.



Telegram offers a solid, secure messaging service. Like Slack, Telegram offers the ability to create bots that can interact with users. We have seen some basic features that bots can do, but we can make them smarter and more functional, take a look at the API of Telegram and be creative. If you make something great share it with us.

  • Elio Qoshi

    Great reference article. To the point and easily to be followed by beginners, good stuff!

  • Paul Bobito

    Is there, by any chance, a way to create something similar for Threema (using their Gateway)?

  • Patrick Catanzariti

    This made me seriously consider getting back into Ruby. I’ll restrain myself right now but building a bot with it looks like a TONNE of fun. Great article dude.

  • Ardian Haxha

    DigitalOcean is what I use to host, I have also tried OpenShift inside a Sinatra app.

    • pablo campos

      digitalocean or openshift? which you recommend to me?
      can I use heroku?

      • Ardian Haxha

        In DigitalOcean you need to make the production environment, though there are some Rails ready images. Yes you can use Heroku, it’s also very easy to host it as a Sinatra app.

  • Muhammad Azamuddin

    How do you set the URL of our server for the bot to communicate?

    • Ardian Haxha

      Hi Muhammad,

      I am not sure I understand your question correctly. You set your API token when you get from BotFather: token = ‘YOUR API TOKEN’ this way you can communicate with your bot. Hope that answers the question.

  • pablo campos

    I like this. but this bot its complete?
    can the bot to dialog with me of everything?
    I want make one, need I a hosting?

  • Tasha Struble

    I consider myself very new / beginner to this, and might just be me being a derp, but it seems (as with most guides ive looked at) there has been some steps missed?

    • Ardian Haxha

      The API has changed and could potentially require some extra steps, I haven’t checked the changes.

  • JIMz z

    just tried your code, but it says :

    /var/lib/gems/2.3.0/gems/telegram-bot-ruby-0.7.2/lib/telegram/bot/api.rb:69:in `call’: Telegram API has returned the error. (ok: “false”, error_code: “409”, description: “Conflict: can’t use getUpdates method while webhook is active”) (Telegram::Bot::Exceptions::ResponseError)

    any ideas?
