Usable by Users Bots
  • chat_id (int | str) – Unique identifier (int) or username (str) of the target chat. For your personal cloud (Saved Messages) you can simply use “me” or “self”. For a contact that exists in your Telegram address book you can use his phone number (str).

  • max_id (int, optional) – The id of the last message you want to mark as read; all the messages before this one will be marked as read as well. Defaults to 0 (mark every unread message as read).


bool - On success, True is returned.


# Mark the whole chat as read
