Platform Quick Reference

Core Patterns

WhatsApp Business Cloud API

// Webhook verification + message handler
import { Hono } from 'hono';
const app = new Hono();

app.get('/webhook/whatsapp', (c) => {
  const mode = c.req.query('hub.mode');
  const token = c.req.query('hub.verify_token');
  const challenge = c.req.query('hub.challenge');
  if (mode === 'subscribe' && token === process.env.WA_VERIFY_TOKEN) {
    return c.text(challenge!);
  }
  return c.text('Forbidden', 403);
});

app.post('/webhook/whatsapp', async (c) => {
  const body = await c.req.json();
  const message = body.entry?.[0]?.changes?.[0]?.value?.messages?.[0];
  if (message?.type === 'text') {
    await sendWhatsAppReply(message.from, `Echo: ${message.text.body}`);
  }
  return c.text('OK');
});

async function sendWhatsAppReply(to: string, text: string) {
  await fetch(`https://graph.facebook.com/v21.0/${process.env.WA_PHONE_ID}/messages`, {
    method: 'POST',
    headers: {
      Authorization: `Bearer ${process.env.WA_ACCESS_TOKEN}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({ messaging_product: 'whatsapp', to, type: 'text', text: { body: text } }),
  });
}

Telegram Bot

import { Bot, InlineKeyboard } from 'grammy';

const bot = new Bot(process.env.TELEGRAM_BOT_TOKEN!);

bot.command('start', (ctx) => ctx.reply('Welcome! How can I help?'));
bot.on('message:text', async (ctx) => {
  const aiResponse = await generateAIResponse(ctx.message.text);
  const keyboard = new InlineKeyboard()
    .text('👍 Helpful', 'feedback_good')
    .text('👎 Not helpful', 'feedback_bad');
  await ctx.reply(aiResponse, { reply_markup: keyboard });
});

bot.callbackQuery('feedback_good', (ctx) => ctx.answerCallbackQuery('Thanks!'));
bot.start();
