How to pull up the phone from telegrams?

Question

Python

Good afternoon!
The task is to filter the base of 42,000 people with usernames and phone numbers by interests
. To do this, we create a bot (still TK)

A person presses the start.
There are three buttons in front of it. Scenario 1 Scenario 2 Scenario 3

Selects scenario 1 - presses

reads the scenario and presses "take part"

in this way some part will go with interest according to scenario one, and some according to others

The task is to create a database.

Questions:

1 Whether it is possible to make so that in a DB the name was pulled up?
2 Is it possible to make the phone pull up in the database?
3 Is it possible to make the username pull up in the database?

In order not to ask a person to drive this data. Please only provide your email address.
Thus, there is less loss of people with our "type of automation"

I understand that if you enter in the field and click send, then you can save the data to the database, but here you need to reduce the number of stages.

Thanks for the answer

Answer 1

1 Is it possible to make the name pull up in the database?
Yes
2 Is it possible to make the phone pull up in the database?
The phone number can be obtained only through a request, or a person will click to share the phone, or you need to make a share phone button
3 Is it possible to make the username pull up in the database?
Yes
In the cart, find the @ShowJsonBot bot and send him a message, in response you will receive JSON with those fields that can be pulled out.
