Sending messages with Telegram - APIs or CLI?

I would like to be able to send a message to a group chat in Telegram. I want to run a python script (which makes some operations that already works) and then, if some parameters have some values the script should send a message to a group chat through Telegram. I am using Ubuntu, and Python 2.7

I think, if I am not wrong, that I have two ways to do that:

I think that the first way is longer, so a good idea might be using the Way Two.

In this case I really don't know how to proceed. I don't know lots about scripts in linux, but I tried to do this: 

#!/bin/bash
cd /home/username/tg
echo "msg user#******** messagehere" | ./telegram
sleep 10
echo "quit" | ./telegram

this works at a half: it sends the message correctly, but then the process remains open. And second problem, I have no clue on how to call that from python and how to pass some value to this script. The value that I would like to pass to the script is the "messagehere" var: this would be a 100/200 characters message, defined from inside the python script.

Does anyone has any clues on that? Thanks for replies, I hope this might be useful for someone else.

Here I have ported @ChrisBrand's very handy and minimal answer, which worked in Python 2, to Python 3. The original also didn't work out-of-the box, so I've automated the extraction of a proper chat-id parameter, which allows you to respond to the sender of the first message you read. Note that this will fail if you haven't received any messages so far, etc.

Finally, I read the bot_id out of the environment so it doesn't have to appear insecurely in any source code. To use this, at least from Linux, first do export TELEGRAM_TOKEN=<value via botfather>

import os
import json
from urllib.request import urlopen
from urllib.parse import urlencode

# Generate a bot ID here: https://core.telegram.org/bots#botfather
bot_id = os.getenv('TELEGRAM_TOKEN')

# Request latest messages
result = urlopen(f"https://api.telegram.org/bot{bot_id}/getUpdates").read()
print(result)

# Extract the chat-id for replying to the first message provided.
chat_id = json.loads(result)["result"][0]["message"]["from"]["id"]

# Send a message back 
result = urlopen(f"https://api.telegram.org/bot{bot_id}/sendMessage", urlencode({ "chat_id": chat_id, "text": 'my message' }).encode('utf-8')).read()
print(result)

I would recommend the first option.

Once you are comfortable with generating an AuthKey, you should start to get a handle on the documentation.

To help, I have written a detailed step-by step guide of how I wrote the AuthKey generation code from scratch here.

It's in vb.net, but the steps should help you do same in python.

Telegram recently released their new Bot API which makes sending/receiving messages trivial. I suggest you also take a look at that and see if it fits your needs, it beats wrapping the client library or integrating with their MTProto API.

import urllib
import urllib2

# Generate a bot ID here: https://core.telegram.org/bots#botfather
bot_id = "{YOUR_BOT_ID}"

# Request latest messages
result = urllib2.urlopen("https://api.telegram.org/bot" + bot_id + "/getUpdates").read()
print result

# Send a message to a chat room (chat room ID retrieved from getUpdates)
result = urllib2.urlopen("https://api.telegram.org/bot" + bot_id + "/sendMessage", urllib.urlencode({ "chat_id": 0, "text": 'my message' })).read()
print result

Unfortunately I haven't seen any Python libraries you can interact directly with, but here is a NodeJS equivalent I worked on for reference.

Since version 1.05 you can use the -P option to accept messages from a socket, which is a third option to solve your problem. Sorry that it is not really the answer to your question, but I am not able to comment your question because I do not have enough reputation.

I'm working with pytg which could be found here: A Python package that wraps around Telegram messenger CLI

it works pretty good. I already have a python bot based on that project

You can use safe_quit to terminate the connection instead since it waits until everything is done before closing the connection and termination the application

#!/bin/bash
cd /home/username/tg
echo "msg user#******** messagehere\nsafe_quit\n" | ./telegram

use this as a simple script and call it from python code as the other answer suggested.

First create a bash script for telegram called tg.sh:

#!/bin/bash
now=$(date)
to=$1
subject=$2
body=$3
tgpath=/home/youruser/tg
LOGFILE="/home/youruser/tg.log"
cd ${tgpath}
${tgpath}/telegram -k ${tgpath}/tg-server.pub -W <<EOF
msg $to $subject
safe_quit
EOF
echo "$now Recipient=$to Message=$subject" >> ${LOGFILE}
echo "Finished" >> ${LOGFILE}

Then put the script in the same folder than your python script, and give it +x permission with chmod +x tg.sh

And finally from python, you can do:

import subprocess
subprocess.call(["./tg.sh", "user#****", "message here"])
