I just want a way to get the messages that my Telegram bot has posted in a private channel where it is an admin. I found this question from over 3 years ago:
Is there any way to get all messages that a Telegram Bot has sent
They say it wasn't possible at the time. I'm wondering if it is possible now.
No, it's still not possible. The only way to get old messages is to use the Telegram client APIs. With these APIs you can do everything a normal user can do (including obtaining the chat history).
Another method is to save the messages the bot send to the channel in a database or in a file for future use, but obviously you won't be able to get the messages you didn't save.
