I am new to the Telegram API. I would like to automate posting messages to my public telegram channel. I read a few posts that with bots I can achieve this, but I am not sure if that's the best way and whether the API has an option to directly post to a channel.
I would like to get some start points on how to achieve this? Which API should I use? Whether I need a dev account or bot, etc?
You can use bots to send message to channels. But there is some limitation, like size of files.
