Question

API

Let's imagine the situation: The user invited my bot to a conversation, and the bot responds to the invitation with something?

Answer 1

Yes, you are tracking the chat_invite_user event , where member_id == bot id .
The bot sees that it was he who was invited, and then you take any action on this condition.
