Sending a notification message to Telegram using its HTTP API via cURL
  1. Create a bot
  2. Get the bot's API token from @BotFather
  3. Add your bot to the chat you'll be sending messages to
  4. Get the ID of the chat
    a. Fetch bot updates and look for the chat id:
    curl https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/getUpdates | -r '.result[].message.chat.id'
    b. OR, run bot.rb and @-mention your bot in the chat. The chat id will appear in bot.rb's output.
    The bot may need temporary message access: @BotFather > Bot Settings > Group Privacy > Turn off
  5. Send a message using the HTTP API: https://core.telegram.org/bots/api#sendmessage
    curl -X POST \
         -H 'Content-Type: application/json' \
         -d '{"chat_id": "123456789", "text": "This is a test from curl", "disable_notification": true}' \
         https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/sendMessage
# Use this script to test that your Telegram bot works.
#
# Install the dependency
#
# $ gem install telegram_bot
#
# Run the bot
#
# $ ruby bot.rb
#
# Send a message to the bot to get the current chat's ID in the console output.
# If it's a group chat, invite them to the chat first.
require 'logger'
require 'telegram_bot'
TELEGRAM_BOT_TOKEN = "YOUR_BOT_API_TOKEN"
bot = TelegramBot.new(token: TELEGRAM_BOT_TOKEN, logger: Logger.new(STDOUT))
bot.get_updates(fail_silently: true) do |message|
puts "@#{message.from.username}: #{message.text}"
puts "Chat-ID: #{message.chat.id}"
end

In Windows I use a small BAT with the help of UnxUtils:

SET TOKEN_BOT=XXXXXXXXXX:YYYYYYYYYYYYYY_ZZZZZZZZZZZZZZZZZZZZ
SET ID_CHAT=-000000000
SET URL=https://api.telegram.org/bot%TOKEN_BOT%/sendMessage
SET MESSAGE="Hello from my Windows"
curl -v -X POST --silent --output /dev/null %URL% -d chat_id=%ID_CHAT% -d text=%MESSAGE%

And in UNIX I use the following SHELL which works very well for me:

#!/bin/bash
TOKEN="XXXXXXXXXX:YYYYYYYYYYYYYY_ZZZZZZZZZZZZZZZZZZZZ"
ID_CHAT="-000000000"
URL="https://api.telegram.org/bot$TOKEN/sendMessage"
SET MESSAGE="Hello from my Solaris"
curl -X POST --silent --output /dev/null $URL -d chat_id=$ID_CHAT -d text="$THE_MESSAGE"
exit 0

You only have to change the Token of the BOT and the ID_CHAT.

Regards.

Yes see https://core.telegram.org/bots/api#sendmessage
add: -d disable_notification=true

Ohhh. thank you very much dear friend. Your answer was really useful for me. I have tried it and it works.

Would it be possible to deactivate the notification within a specific time via curl? This would be great for me, but I'm not sure if it would be possible. Thanks in advance. a cordial greeting

I think at that moment you are either better of writing a shell script or writing it in another programming language

If you are getting an empty result list when doing getUpdates for your bot, kick the bot out of the group, invite again and fetch again.

Very useful. Made a neat little script that you can import in bash. Adds a title/timestamp to it. Keeps me informed whenever my deployments need my attention.

#!bin/bash

TELEGRAM_BOT_TOKEN="botid:token"
CHAT_ID="1234567890"

send_telegram () {
    title="$1"
    timestamp="$(date -R)"
    msg="$title\n$timestamp\n\n$(echo "$2" | sed -z -e 's|\\|\\\\|g' -e 's|\n|\\n|g' -e 's|\t|\\t|g' -e 's|\"|\\"|g')"
    entities="[{\"offset\":0,\"length\":${#title},\"type\":\"bold\"},{\"offset\":$((${#title}+1)),\"length\":${#timestamp},\"type\":\"italic\"}]"
    data="{\"chat_id\":\"$CHAT_ID\",\"text\":\"$msg\",\"entities\":$entities,\"disable_notification\": true}"
    curl -s -o /dev/null -H 'Content-Type: application/json' -d "$data" -X POST https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/sendMessage
}

Import with source /path/to/telegram.sh then can call the function each time you want to send a message like so send_telegram "title in bold" "this is the message body".
Output:
title in bold
Sat, 07 Oct 2022 00:24:57 +0100
this is the message body

The right curl:

curl -s https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/getUpdates | jq -r '.result[].message.chat.id'

yes

curl -X POST https://api.telegram.org/bot/sendDocument -F chat_id='123456789' -F document=@'/path/to/file' -F caption='source: https://example.com'

Instead of:

curl https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/getUpdates | jq .message.chat.id

I think it should be:

curl https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/getUpdates | jq 'result[].message.chat.id'

Found myself in need to send an arbitrary text with unicode and quotes, the original example didn't work.

Here is updated one, forcing jq to do all of the string escaping:

#!/usr/bin/env bash
# noti-bot - send notification in telegram
# Usage:
#   echo "your text" | noti-bot
# or
#   noti-bot "your text" | noti-bot

API=yours
chat_id=yours

if [[ -n "$1" ]]; then
    msg="$1"
else
    msg="$(cat)"
fi


# to escape " and unicode, no, printf is not enough, neither is multiple -d for curl
data="$(echo '{"chat_id": "aaa", "text": "aaa", "disable_notification": false}' |
    jq --arg msg "$msg" --arg chat "$chat_id" '{"chat_id": $ARGS.named.chat, "text": $ARGS.named.msg, "disable_notification": false}')"

# echo "$data"

ans="$(curl -s --tlsv1.2 -X POST \
     -H 'Content-Type: application/json' \
     -d "$data" \
     https://api.telegram.org/bot$API/sendMessage)"

if [[ "$(echo "$ans" | jq -r '.ok')" != "true" ]]; then
    echo "$ans" | jq -r '"error \(.error_code) - \(.description)"'
fi

Demo:

echo -e 'Nope!";$(pwd)"\nyes - приветこんにちは' | ./noti-bot

I know, I know, "at this point just use python or something". I needed it with curl.

If succesful - prints nothing.
If not - prints "error_code - error_description".
