Telegram Bot ChatId Value must not be empty and [400] Bad Request: chat not found

Questions

Description:
I’m trying to send a message from Make.com to my private Telegram chat using the “Send a Message” module. However, I’m getting the error:
[400] Bad Request: chat not found

Also tried to create a connection with private chanel with a chat id, but got this error: Value must not be empty. I’m sure that everything was correct.

What I’ve tried so far:
:white_check_mark: Sent /start to the bot manually.
:white_check_mark: Verified my Chat ID using getUpdates API.
:white_check_mark: Checked that the bot is not blocked in my Telegram settings.
:white_check_mark: Tested sending a message manually via Telegram API

Problem:
Despite everything working fine via the API, Make.com still gives the [400] Bad Request: chat not found error when trying to send messages to my private chat.

Questions:

  1. Is there a known issue with Telegram bots sending messages to private chats in Make.com?
  2. Are there any specific formatting requirements for the Chat ID? (e.g., user_id:712718696 instead of just 712718696?)
  3. Any possible workarounds if this is a bug?

Thanks in advance for any help! :rocket:

Thank you for the clear explanation.

  1. Is there a known issue with Telegram bots sending messages to private chats in Make.com?

As far as I know, there is no problem.

  1. Are there any specific formatting requirements for the Chat ID? (e.g., user_id:712718696 instead of just 712718696?)

I think it is as you have identified. Another way to check is to go to Chat > ID in the Watch Updates Module of Telegram Bot.

However, if it is Private Groups, the ID should be in a format like -123456789. Hyphen is also required.

Other possible causes would be that the bot has not been added to the Group.

I’m having the same problem and have no idea what’s wrong. The private group ID is correct, it uses a “-”; I made sure the bot is added. It’s even a group admin.

I finally created a new bot, gave it full permissions, and checked the group ID. And it worked.
