How to get contacts on Telegram

Question

I use node.js module for Telegram bot. I'm trying to get the user's contact on telegram using telegram API. Telegram API has 2 types: Bot API and Telegram API.

I think Bot API can not get the user's contacts. In Telegram API there is the method contact.getContacts. But I don't know how to use it.

How can I get the contacts on Telegram?

Answer 1

1. this code will give you the contact, user shares his/her contact with your bot , user types command '/special' will be prompted with button to allow bot to get contact and on agreeing in your node server you may log contact info remember to declare Markup ---->

   //declare Markup 
   const {Extra,Markup}= Telegraf;
   
   bot.command('special', (ctx) => {
   return ctx.reply('Special buttons keyboard', Extra.markup((markup) => {
   return markup.resize()
   .keyboard([
   markup.contactRequestButton('contact')
   ])
   }))
   })
   //listens for the click on contact button
   bot.on('contact', (ctx) => {
   console.log(ctx.update.message.contact);
   //logs { phone_number: '254*******',
   //first_name: 'nelsonBlack',
   //user_id: 73***** }
   
   })
