How to implement a share profile button in aiogram like PremiumBot?

Im not sure if it is even possible because i didnt found any info about it in official documentation

Create share profile button like in PremiumBot (I attached photo)

Solution

This feature was added in Bot API 6.5. You can create a button like this using KeyboardButtonRequestUser. This allows you to select user data according to the desired criteria and send it to the bot.

keyboard.py

def button():
    keyboard = types.ReplyKeyboardMarkup(resize_keyboard=True)
    request_button = types.KeyboardButton(text="Select user",
                                  request_user=types.KeyboardButtonRequestUser(
                                        request_id=1
                                    )
                                    )
    keyboard.add(request_button)
    return keyboard

app.py

import logging

from aiogram import Bot, Dispatcher, executor, types

from keyboard import button

API_TOKEN = 'YOUR BOT TOKEN'

logging.basicConfig(level=logging.INFO)

bot = Bot(token=API_TOKEN)
dp = Dispatcher(bot)


@dp.message_handler(commands=['start'])
async def send_welcome(message: types.Message):
    await message.reply("Hi!\nI'm Bot!", reply_markup=button())


@dp.message_handler(content_types=types.ContentType.USER_SHARED)
async def get_shared_user_data(message: types.Message):
    logging.info(message.user_shared.user_id)
    await message.answer(message.user_shared.user_id)


if __name__ == '__main__':
    executor.start_polling(dp, skip_updates=True)
