How to send message from bot to user at a fixed time or at intervals through python telegram bot library?

Question

I am trying to send messages to bot daily without trigger from user side (eg commandhadler) from second conversation onwards.

I have build a basic menu for bot to interact with user

But i am also trying to send messages daily through job_queue

I have refered codes which are using commandhandlers

dp.add_handler(CommandHandler("set", set_timer,
                              pass_args=True,
                              pass_job_queue=True,
                              pass_chat_data=True))

This is being set after user types /set . But I am trying to find a way to automatically send messages every 30 seconds or set a fixed time for message to be sent daily My code

from telegram.ext import Updater,CommandHandler 
from telegram.ext import  MessageHandler,Filters,InlineQueryHandler
import logging
import telegram

logging.basicConfig(level=logging.INFO,
                    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s')
logger = logging.getLogger()

def start(bot, update):
    update.message.reply_text("Hello , Thanks for choosing us!!")

def callback_minute(context: telegram.ext.CallbackContext):
    chat_id = ?
    context.bot.send_message(chat_id=chat_id, 
                             text='Hi User, Add Fund to your account to start trading')


def main():
    updater = Updater(token,use_context=True)
    dp = updater.dispatcher
    j = updater.job_queue
    dp.add_handler(CommandHandler("start",start))
    job_minute = j.run_repeating(callback_minute, interval=10, first=0)

    updater.start_polling()

    updater.idle()

How to get chat_id? If i am using

def callback_minute(update, context: telegram.ext.CallbackContext):
    chat_id = update.message.chat.id

I am getting this error

TypeError: callback_minute() missing 1 required positional argument: 'context'

You cannot get `chat_id` in this way. `chat_id` can be obtained only from `update` object, and `update` object will be fetched only when user sends a message to Bot. First, move the job_queue lines to a separate function. Then this function should be called using any Handlers. — Gagan T K, Jan 07 '20 at 09:25

How do you want to start this job of sending messages? What should be the triggering point for this? — Gagan T K, Jan 07 '20 at 09:42

It is reworked below so that run_repeating() is called from the /start command (as suggested by Gagan T K in the comments). In this example first=30 so it will start after 30 seconds.

There is a good example of using the job queue in this way at the bottom of the wiki documentation for JobQueue on GitHub.

from telegram.ext import Updater,CommandHandler 
from telegram.ext import MessageHandler,Filters,InlineQueryHandler
import logging
import telegram

logging.basicConfig(level=logging.INFO,
                    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s')
logger = logging.getLogger()

bot = telegram.Bot(token=token)

def start(update, context):
    context.bot.send_message(chat_id=update.message.chat_id,
                     text="Hello , Thanks for choosing us!!")

    context.job_queue.run_repeating(callback_minute, interval=10, first=30,
                                    context=update.message.chat_id)

def callback_minute(context):
    chat_id=context.job.context
    context.bot.send_message(chat_id=chat_id, 
                             text="Hi User, Add Fund to your account to start trading")

def main():
    updater = Updater(token,use_context=True)
    dp = updater.dispatcher
    dp.add_handler(CommandHandler("start",start, pass_job_queue=True))

    updater.start_polling()

    updater.idle()

if __name__ == '__main__':
    main()

You have to use context.job_queue.run_repeating() to repeat the job continuously after specific time interval.

If you want the job to execute once everyday, you can use context.job_queue.run_daily() and specify the time.

These are python-telegram-bot docs links for both of the cases: job_queue.run_repeating(), job_queue.run_daily()

These docs have very good information which will help your query.
