Run your own Bot API server

You can run Bot API locally and send the requests to your own server instead of api.telegram.org. If you switch to a local Bot API server, your bot will be able to:

- Download files without a size limit.
- Upload files up to 2000 MB.
- Upload files using their local path and the file URI scheme.
- Use an HTTP URL for the webhook.
- Use any local IP address for the webhook.
- Use any port for the webhook.
- Set max_webhook_connections up to 100000.
- Receive the absolute local path as a value of the file_path field without the need to download the file after a getFile request.

The source code of the Telegram Bot API server is licensed under the Boost Software License.

Transferring ownership of bots
⁠⁠⁠⁠
Along with the update Bot API to version 5.0, it became possible to transfer ownership of a bot from one account to another.

For transmission:
- Two-factor authentication must be enabled at least 7 days prior to transfer. The password should not change during this time.
- The session from which the transfer takes place must exist for at least 24 hours.
- The user to whom the transfer is carried out must write to the bot and unblock it (if the bot was blacklisted by the user).

The transfer is carried out through the bot @botfather.
