How to write a bot for telegram?

Question

Bots

I want to do such a thing, so that, for example, when a new user registers on the site, a notification arrives in the telegram. How to implement it? Are there any articles? or video?

Answer 1

What are the difficulties? Write the code for you?
Options:
1. After registering a user, the site executes a script, it collects the completed information and sends it to a fixed ID in plain text
2. Once a minute, go through the cron and check if new users have appeared in the database. If yes - send a message to yourself with the data, if not - the bot is silent.
