Why telegram group automatically becomes super group? – Telegram API

My telegram bot is a member of several groups. I use it to send different kind of incident notifications to different telegram groups. Today i noticed couple of my telegram groups automatically became super group. Thus their chat id changed. So my message sending was failed. By the time i found out that the chat id has changed a lot of notifications were missed.

This messages are fired automatically. So if the chat id changes automatically then it is a problem for me.

I have couple of questions to understand the cause.

  1. Why telegram groups becomes supergroups ?
  2. How many ways chat id of a chat in telegram can change ?
  3. Does telegram channel’s chat id can be changed ? (If no then i will stop using groups. I will use channel)

I have browsed google and telegram bot api documentations. But i could not find my answers.

I know if a group chat is migrated to super group then upon sending the next message with the old chat id, i will get a response from telegram with the new chat id. Then i can update the chat id. But i want to avoid this way of updating the chat id. I would like my group chat id to remain same forever.

    1. Telegram updated their groups with their update from 22/01/19. Maybe this caused the Id change

    As of today, supergroups and basic groups are simply groups. It now
    takes just a few taps to make any group public, add admins with
    granular privileges or toggle persistent history.

    1. I do not think the chat Id will change again (if there isn’t a breaking change like the last update)

    2. All Id’s can be changed eventually. It depends on Telegram. But as I said it is really unlikely that Id’s change that often neither for groups nor for channels.

    The answer can be found here.

    • making the group public
    • changing a user’s permissions
    • changing an admin’s permissions
    • changing group history visibility
    • the 201st member joins

    will convert the group to supergroup automatically.
