Telegram payment with stripe

在Bot father選擇Edit bot->Payments->Stripe，可以選擇Connect Stripe Test或者Connect Stripe Live

跳到對應的Stripe bot後，按提示完成認證後會得到payment token

使用node-telegram-bot-api

import TelegramBot from "node-telegram-bot-api";

const botToken = "TELEGRAM BOT TOKEN";
const paymentToken = "STRIPE_TOKEN";

const bot = new TelegramBot(botToken, { polling: true });

const productID = "P_ID_1";

bot.onText(/\/start/, (msg) => {
  const chatId = msg.chat.id;
  bot.sendMessage(
    chatId,
    "Welcome to the payment bot. Use /pay to initiate a payment."
  );
});

bot.onText(/\/pay/, (msg) => {
  const chatId = msg.chat.id;
  const payKeyboard = {
    reply_markup: JSON.stringify({
      inline_keyboard: [
        [
          {
            text: "Pay $10 HKD",
            callback_data: productID,
          },
        ],
      ],
    }),
  };

  bot.sendInvoice(
    chatId,
    "Title"
    "Description",
    "Invoice for payment", //payload
    paymentToken ,
    "HKD",
    [{ label: "Product Name", amount: 1000 }], //amount in cents (amount*100)
    [payKeyboard]
  );
});

bot.on("pre_checkout_query", (msg) => {
  /*This function is required by telegram payment, after user perform paymend, this funciton will be called to check the goods is available*/
  const queryId = msg.id;
  bot.answerPreCheckoutQuery(queryId, true);
});

bot.on("successful_payment", (msg) => {
  const chatId = msg.chat.id;
  console.log("Payment success.")
});
