Can i get a phone number by user id via Telegram Bot API?

Question

I'm using Telegram Bot API for sending instant messages to users. I've installed nuget package. This package is recommend by telegram developers.

I've created a telegram bot and successfully got access to it by using code. When I send messsage to bot, bot gets some info about sender.

I need the phone numbers of users to identify them in our system and send the information back to them.

My question is Can i get a user phone number by telegramUserId ?

I'm doing it for user convenience. If i could to get a user phone number I should't have to ask for it from the user.

now my command like this:

debt 9811201243

i want

debt

Answer 1

No, unfortunately Telegram Bot API doesn't return phone number. You should either use Telegram API methods instead or ask it explicitly from the user. You cannot get "friends" of a user as well.

You will definitely retrieve the following information:

1. userid
2. first_name
3. content (whatever it is: text, photo, etc.)
4. date (unixtime)
5. chat_id

If user configured it, you will also get last_name and username.

It's possible with bots 2.0 check out bot api docs.
