Creating a telegram bot for notification?

Question

Telegram

Good afternoon, can you tell me if it is possible to create a telegram bot to notify customers about the progress of their order?
That is, in CRM there is a client number, I want to notify the client via telegrams. Is this possible or does the recipient have to be in a group or a subscription to the bot?

Answer 1

Yes, the recipient must be in a group or subscribed to the bot. Some sites offer to link an account on the site to a bot in order to receive notifications, but this is not very convenient.
