My first Telegram Bot

TL;DR This post is kind of a protocol of the initial setup of our Telegram Planets bot. In about 10 minutes you'll be able to send notifications to a chat with curl.

Don't waste time. Let's get started!

Q: How do I create a bot? Start a chat with ... the Botfather

Creating a new bot is a easy as /newbot and answering some question.

You'll get a URL like<your_bot_name>_bot and a token for the HTTP API.

And a hint where to go next: "For a description of the Bot API, see this page:"

To give the bot a bit more personality the Botfather offers some more commands:

command description
/setname change a bot's name
/setdescription change bot description
/setabouttext change bot about info
/setuserpic change bot profile photo
/setcommands change the list of commands

Let's look around in the Telegram Bot API...

All requests basically have the following format:<token>/METHOD_NAME

Calling getMe reveals basic information about our bot:

$ curl -X GET
    "ok": true,
    "result": {
        "id": 123456,
        "is_bot": true,
        "first_name": "PlanetsFather",
        "username": "planets_father_bot"

That was easy...maybe we should getUpdates now?

    "ok": true,
    "result": []

As promised by the docs another JSON document "which always has a Boolean field ‘ok’". No updates - We have to start a chat with our fresh bot:


and try again getUpdates

    "ok": true,
    "result": [
            "update_id": 630248673,
            "message": {
                "message_id": 7,
                "from": {
                    "id": 1234,
                    "is_bot": false,
                    "first_name": "planets",
                    "language_code": "en-US"
                "chat": {
                    "id": 171765575,
                    "first_name": "planets",
                    "type": "private"
                "date": 1504891788,
                "text": "Hello"

Now extract the chat id 17165575. This is where our notifications should go to as well.

We are good to go for push notifications to the chat. Let's sendmessage to the chat

$ curl -X POST \
    -H 'content-type: application/json' \
    -d '{ "chat_id": 171765575, "text": "Hello from Planets bot" }'

Nice. The initial setup is done. Stay tuned...
