forward-telegram-message

Mirror Telegram messages between two chats using Telethon — runs as a user-account, not a bot.

Quick start

cp .env.example .env
# Fill in PHONE, API_ID, API_HASH, SOURCE_GROUP_ID, TARGET_GROUP_ID
pip install -r requirements.txt
python main.py

Get API_ID and API_HASH from my.telegram.org.

Configuration

Variable	Required	Description
PHONE	Yes	Your Telegram phone number (e.g. +84912345678)
API_ID	Yes	App API ID from my.telegram.org
API_HASH	Yes	App API hash from my.telegram.org
SOURCE_GROUP_ID	Yes	ID of the source chat/group to mirror from
TARGET_GROUP_ID	Yes	ID of the destination chat/group to forward into

Notes

• Runs as a user account (Telethon), not a bot — requires first-time interactive login to generate a session file.
• Forwards both text messages and media (photos, documents, videos).
• Re-uses the session file on subsequent runs; no re-auth needed.
• SOURCE_GROUP_ID and TARGET_GROUP_ID can be negative (supergroup IDs) or positive (private chat IDs).
