telegram-bot-dumper

Easy dumping of all Telegram bot stuff.

Input: only bot token.

Output: bot name & info, all chats text history & media, bot's users info & photos.

Requirements

Python >= 3.6
Telethon >= 1.24.0
Register Telegram application to get API_ID and API_HASH

Using

pip install -r requirements.txt

vi dumper.py # change API_ID and API_HASH and save

./dumper.py --token 12345678:ABCe2rPVteUWZ7wLeCqCb3CH3ilUY_fLabc

Also you can use --tor flag for Telegram blocking bypass.

Testing

You can ask me for bot testing token.

TEST_TOKEN=... python3 -m pytest bot_test.py

Currently known issues

Bot is exiting with not fully dumped history

Some messages can be deleted by bot users. If you suppose that the history was not completely dumped, specify cycles count to skip empty messages (200 per cycle by default):

# check additionally 5*200 = 1000 messages

./dumper.py --token 12345678:ABCe2rPVteUWZ7wLeCqCb3CH3ilUY_fLabc --lookahead 5

History was not dumped for chats

I don't know the solution to this problem. :(

Token leaks
