You cannot get the chat history of a channel using the bot API. However you can use the core API (tdlib etc) to get the chat history. Alternatively you can try and scrape from the posts widget , but that is going to be too tedious.

but when I am using getupdates method it shows all the message with all channel.

You can manually filter out the channels since the ID is always in the Update object. I would suggest you use a library for this since it would be easier to implement the logic.
