Telegram was predominantly a cellular software, but also for development purposes you’re going to want it attached to exactly the same device you are really making use of for writing rule. Because of this, you’ll easily test drive it without unlocking their telephone everytime. And, you’ll be able to duplicate and paste your Telegram bot’s API essential straight to your own book editor.
For you personally to seize that API secret!
Step two: talk to the BotFather receive their API key
Telegram bot production is actually an unique proce because a lot of truly concentrated around a relationships with a Telegram bot. That robot is the BotFather. Inside your Telegram desktop app, you need to bing search their login name and start a conversation with him.
Give the begin command to BotFather by typing /start .
You’ll see a summary of commands which help your write, edit, and control your own spiders. Because it’s very first energy, you’ll need /newbot .
Compared to the proce for constructing 
a Twitter robot, a Mastodon robot, or just about any other kind of robot I’ve attempted, Telegram helps make the original build super easy. We gue that proves what an excellent device Telegram bots may be!
After providing the /newbot command, you are free to pick a name and login name to suit your robot. Title is what the consumers will see the bot like in her associates number, and the username is just how they’ll find it. Think about the login name like a Twitter handle; it should end up being distinctive, plus it’s ideal if it’s small and memorable.
With that complete, you’ll be provided with your own bot’s API secret. The API key was how Telegram knows the rule you write is actually aociated using this type of robot. Every bot has its own API trick, and you ought ton’t communicate it with any individual or they can hijack their bot and just have it perform their particular wicked deeds.
That concludes the talk to BotFather for the time being — onto the signal!
3: creating the bot’s jewels and directory
Open terminal, and perform mkdir telegram-bot . This brings a brand new index for the bot’s data. It’s best to keep them confined to one folder as a result it’s an easy task to regulate. Demand directory with cd telegram-bot immediately after which carry out the utilizing:
touch Gemfile touch bot.rb atom .
This produces two blank data, one for indicating the treasures you’ll need and another where in actuality the bot’s signal will reside. The very last demand opens up both these data in Atom.
Click on the Gemfile in Atom’s sidebar, and paste these in:
This says to Bundler to seize the Ruby software for the Telegram API from rubygems.
To perform the jewel create, go back to your own terminal and kind package . Here’s what you ought to see:
That’s it the jewel build, today we’re finally getting on the signal.
Coding your first Telegram robot
The particular laws that will getting running constantly from the servers try inside bot.rb. It’s bare right now, but right here we’re planning link within the Telegram jewel we simply included and create a bot.
It’s little code to write. By the time you are really finished, this is exactly what you’ll have:
In Telegram, this is exactly what the laws above really does:
Let’s take a look at what every part of the signal does and write it we run.
(Replace the TOKEN making use of the API token you duplicated from BotFather)
Ruby helps it be simple to gue what code will perform. The three contours above create the Telegram bot function to your file and generate another robot item from Telegram robot cla, authenticated along with your token so the program understands the best place to send the information.
The next part is the one big circle. It appears confusing initially, nevertheless’s easy to choose apart.
The initial range informs the robot to keep hearing for commands. And, when it get a command to pa they for the meage variable. The leaves line logs the order your terminal in order to discover what’s going on whilst bot operates.
The bot’s response measures tend to be stored in a case declaration. Happening statement’s insight was fed through through the meage changeable after it’s become washed right up because of the gem’s get_command_for system. The bot’s reply text is placed depending on the order saved and at long last delivered with send_with prior to the loop restarts.
With this specific setup, now you can find their robot on Telegram and send the /start and /greet commands, watching they in action.
For this, save the changes in Atom and operated ruby bot.rb within the terminal. Provided that terminal was open and running, the robot will be sending responses!
