A comprehensive official documentation can be found here.

Python 3.X and telegram-bot 5.6 message forwarding is not working – Telegram API

Scenario: I am writing a bot to transfer couple of selected messages from a private channel to the person(which I have his/her I) or to another group that I have its id

Status:

  • Bot: Admin of my private channel.(from part or source): (id=-15XXXXXX)

  • Bot: Privacy mode is off

  • Bot: normal member of forwarding to group (to part or sink) (I have the id as well)

  • me: Admin of private channel

  • me: normal member

  • user: I have his/her telegram id (I have the id as well)

Following is the code of forward function

    def forwardMsg(self, update: Update, context: CallbackContext):
            context.bot.forwardMessage(chat_id=update.effective_chat.id, 
            from_chat_id=-15XXXXXX, message_id=4463)

Following is my main code

    forwardMsg_handler = CommandHandler('forwardMsg', forwardMsg)
    dispatcher.add_handler(forwardMsg_handler)

All other commands are working.

I get following error in Pycharm console

telegram.error.BadRequest: Chat not found

I searched everywhere, It must work but it doesn’t. WHY?

    Base on CallmeStag input, I couldnt find any -100 at the beginning of

    • Channel link
    • Copy Post link parts. However there was a gist on github which was mentioning that we have to add -100 as prefix to the channel ID.

    Therefore the solution is -100 + channel ID taken from Copy Post Link as an integer for from_chat_id

    As already answered on this GitHub thread, you should double check the channel ID as channel IDs start with a -100.
