function createInvoiceLink not exist

[tieudat]

I don't use function createInvoiceLink in TelegramBot => My code: const TelegramBot = require("node-telegram-bot-api");

Your example @tieudat is not a full example... So normal that dont works, you dont create a instance. Only import the api, but you need to use it.

This is basic example:

// Import the library
const TelegramBot = require('node-telegram-bot-api');

// Replace the value below with the Telegram token you receive from @BotFather
const token = 'YOUR_TELEGRAM_BOT_TOKEN';

// Create bot that uses 'polling' to fetch new updates
const bot = new TelegramBot(token);

// Now call the function
const title = 'Invoice link product';
const description = 'Our test invoice link product';
const payload = 'sku-p002';
const providerToken = XXXXX.....; // Token of your payment provider get it form botfather bot config 
const currency = 'EUR';
const prices = [{ label: 'NTBA API', amount: 12000 }, { label: 'tax', amount: 10000 }];
      
bot.createInvoiceLink(title, description, payload, providerToken, currency, prices).then(resp => {
       console.log("Invoice Link", resp)
 });
