tgsupportbot

A Telegram support bot that forwards messages from users to a group chat, allowing a support team to respond privately.

How it works

Users message the bot directly. The bot forwards each message to a configured support group (optionally into a specific topic thread). Support staff reply in the group by replying to the forwarded message; the bot delivers the reply back to the user.

If a message goes unanswered, the bot sends a reminder to the group every 6 hours until the conversation is marked finished.

Setup

Docker (recommended)

docker build -t tgsupportbot .
docker run -d \
  -v /path/to/config.yaml:/config.yaml \
  -v /path/to/data:/data \
  tgsupportbot

Set database: "/data/instance.db" in your config so the database persists outside the container.

Manual

Requirements: Python 3, pip

pip install -r requirements.txt

Copy config.yaml.example to config.yaml and fill in the values (see Configuration below).

Create a bot via @BotFather, add it to your support group, and give it permission to read and send messages.

python -m supportbot -c config.yaml

Group commands

All commands are issued in the support group by replying to a forwarded message.

Command	Description
`/info`	Show the user's name, username, and ID
`/ban`	Ban the user permanently
`/ban 7d`	Ban the user for a duration (`s`, `m`, `h`, `d`, `w`)
`/unban`	Unban the user
`/finished`	Mark the conversation as resolved and stop reminders

Reminders

When a user sends a message, the bot starts a reminder timer. If /finished has not been used before the interval elapses, a reminder is posted to the group. Reminders repeat at the same interval until /finished is used. The timer resets if the user sends another message.
