How to get information about a new subscriber to a channel in telegram?

Question

Bots

Is it possible for a bot to get data about a new subscriber (at least his id) on the telegram channel where this bot will be placed.

I work with bot-api through Aiogram. I didn’t find such a method in the documentation, maybe I didn’t look for it well, or maybe there’s no such functionality at all, but then the bot for the channel is useless, because it had to send the contact of the new subscriber to the channel admins one by one. If this is impossible to implement - just write so that you do not waste time in vain.

Thanks for the replies!

Answer 1

The Message object has a new_chat_members field

@dp.message_handler(content_types=types.ContentTypes.NEW_CHAT_MEMBERS)
async def new_chat_member(message: types.Message, chat: Chat):
    # ....

Answer 2

No.
This is done on purpose so that new subscribers are not spammed.
