After setting the name and the username, the bot address and token will be generated and displayed in the chat.
The given token is used for accessing the HTTP API and should be kept safely.
The token can be revoked by using the "/revoke" command.
It is useful to set a bot profile photo using the command "/setuserpic" and a bot description using the "/setdescription" command.
The new Telegram bot is created.
2.2 Setting Up the Telegram Channel in the Business Messenger App
In order to connect the Business Messenger app with Telegram bot that was just created, it is necessary to go to Settings>Channels section.
Clicking on the Edit channels button will open a new window where a channel can be set up.
The given bot token has to be filled out in Bot Token field. Clicking on the Save button will save the token and connect the Business Messenger app with the Telegram API.

2.3 Setting Up Opt-in/Opt-out Rules
In order to tell the Telegram bot what to do, Opt-in/Opt-out Rules should be created in the BM Opt-in/Opt-out Manager>Telegram section.
Creating Opt-in/Opt-out rules is very important. Without defined Opt-in/Opt-out rules and configured keywords, no contacts will be stored, since there is no definition about if and how to store new subscriptions.
In Opt-in/Opt-out Manager Telegram section, clicking on the Add Telegram Opt-in/Opt-out button , will open a new window where, for selected rule Type - Opt-in or Opt-out, a Keyword should be set up. A Keyword is a kind of command that a bot will understand and do a specific action. Telegram bot custom commands start with '/' character. A keyword is a text a Telegram user is expected to send for a rule to be activated and should be unique, meaning that two rules can not have the same keyword.
There should be defined rules for Opt-in and Opt-out for all communication or for some specific subscription.
