Configuring your bot: a config.env and chat_list.json files.

This file should be placed in tzbot folder, alongside the __main__.py file . This is where your bot token will be loaded from, and most of your other settings.

Template env may be found in sample.config.env. Rename it to config.env and fill in the values:

An example config.env file could be:

BOT_TOKEN = 1234567890:Abcdef1234567890GHIJ
OWNER_ID = 1234567890, 0987654321
REMOVE_TAG = True
DEFAULT_LANG = en
APSCHEDULER_LOG_LEVEL = INFO
APSCHEDULER_SCHEDULER_INFO = 0

Template chat_list may be found in chat_list.sample.json. Rename it to chat_list.json.

This file contains the list of chats to forward messages from and to. The bot expect it to be an Array of objects with the following structure:

• source - The chat ID of the chat to forward messages from. It can be a group or a channel.

  If the source chat is a Topic groups, you MUST explicitly specify the topic ID. The bot will ignore incoming message from topic group if the topic ID is not specified.

• destination (Optional) - An array of chat IDs to forward messages to. It can be a group or a channel.

  Destenation supports Topics chat. You can use #topicID string to forward to specific topic. Example: [-10011111111, "-10022222222#123456"]. With this config it will forward to chat -10022222222 with topic 123456 and to chat -10011111111 .

• filters (Optional) - An array of strings to filter words. If the message containes any of the strings in the array, it WILL BE forwarded.

• blacklist (Optional) - An array of strings to blacklist words. If the message containes any of the string in the array, it will NOT BE forwarded.

• delete_after (Optional) - A numeric integral. Defines the time in seconds period after which the message will be deleted.

You may add as many objects as you want. The bot will forward messages from all the chats in the source field to all the chats in the destination field. Duplicates are allowed as it already handled by the bot.

It is also possible to enter several different filters on the same source.

[
  {
    "source": -10012345678,
    "destination": [-10011111111, "-10022222222#123456"]
  },
  {
    "source": "-10087654321#000000", // Topic/Forum group
    "destination": ["-10033333333#654321"],
    "filters": ["word1", "word2"] // message that contain this word will be forwarded
  },
  {
    "source": -10087654321,
    "destination": [-10033333333],
    "blacklist": ["word3", "word4"] // message that contain this word will not be forwarded
  },
  {
    "source": -10087654321,
    "destination": [-10033333333],
    "filters": ["word5"],
    "blacklist": ["word6"],
    "delete_after": 60
    // message must contain word5 and must not contain word6 to be forwarded and deleted after 60 seconds
  },
  {
    "source": -10087654321,
    "delete_after": 2700
    // message from this group will be deleted after 2700 seconds
