A simple Telegram Python bot running on Python3 to automatically forward messages from one chat to another.

Currently, being used in our updates channel to automatically forward messages to all our groups. Originally,Can be found on Telegram as Kustom Updates Bot. My Bot is deployed as Saksham's Bot

Once your configuration (see below) is complete, simply run:

python3 -m auto_forwarder

Please make sure to use the latest Python version. (Recommended)

There are two possible ways of configuring your bot: a config.py file, or ENV variables.

The prefered version is to use a config.py file, as it makes it easier to see all your settings grouped together. This file should be placed in your auto_forwarder folder, alongside the __main__.py file . This is where your bot token will be loaded from, and most of your other settings.

It is recommended to import sample_config and extend the Config class, as this will ensure your config contains all defaults set in the sample_config, hence making it easier to upgrade.

An example config.py file could be:

from auto_forwarder.sample_config import Config


class Development(Config):
    API_KEY = "1234567890:Abcdef1234567890GHIJ"  # My bot API key
    OWNER_ID = 1234567890  # My user id

    # Make sure to include the '-' sign in group and channel ids.
    FROM_CHATS = [-1001234567890]  # List of chat id's to forward messages from.
    TO_CHATS = [-1001234567890 , 1234567890]  # List of chat id's to forward messages to.
    
    WORKERS = 4

If you can't have a config.py file (EG on Heroku), it is also possible to use environment variables. The following environment variables are supported:

• ENV: Setting this to ANYTHING will enable environment variables.

• API_KEY: Your bot API key, as a string.

• OWNER_ID: An integer of consisting of your owner ID.

• FROM_CHATS: Space separated list of chat ID's to forward messages from. Do not forget to include the minus (-) sign in the chat ID's of groups and channels. You can add ID's of users too, to forward their messages with the bot.

• TO_CHATS: Space separated list of chat ID's to forward messages to. Do not forget to include the minus (-) sign in the chat ID's of groups and channels. You can add ID's of users too, to forward messages to them.

• WEBHOOK: Setting this to ANYTHING will enable webhooks when in env mode messages.

• URL: The URL your webhook should connect to (only needed for webhook mode).

• CERT_PATH: Path to your webhook certificate.

• PORT: Port to use for your webhooks.

• WORKERS: Number of threads to use. 4 is the recommended (and default) amount, but your experience may vary.

NOTE: You may need to use more workers if the number of messages to be forwarded are more.

Install the necessary python dependencies by moving to the project directory and running:

pip3 install -r requirements.txt.

This will install all necessary python packages.
