How It Works
Skill para implementar bots profissionais no Telegram usando a Bot API oficial. Suporta Node.js/TypeScript e Python.
Overview
A Telegram Bot API permite criar bots que interagem com usuarios via mensagens, comandos, inline keyboards, pagamentos e muito mais. Bots sao criados pelo @BotFather e autenticados via token unico.
Base URL: https://api.telegram.org/bot<TOKEN>/METHOD_NAME Metodos HTTP: GET e POST Formatos de parametros: query string, application/x-www-form-urlencoded, application/json, multipart/form-data (uploads) Limite de arquivos: 50MB download, 20MB upload (via multipart), 50MB via URL
Portas suportadas para webhooks: 443, 80, 88, 8443
Pre-requisitos:
- Conta no Telegram
- Bot criado via @BotFather (fornece o token)
- Token no formato:
123456:ABC-DEF1234ghIkl-zyx57W2v1u123ew11
Se o usuario nao tem um bot criado, oriente a conversar com @BotFather no Telegram e enviar /newbot.

python scripts/test_bot.py --token "SEU_TOKEN"Para enviar uma mensagem de teste:
python scripts/send_message.py --token "SEU_TOKEN" --chat-id "CHAT_ID" --text "Hello!"Setup Com Botfather
- Abra o Telegram e busque @BotFather
- Envie
/newbot - Escolha nome de exibicao (ex: "Meu Bot Incrivel")
- Escolha username (deve terminar com "bot", ex:
meu_incrivel_bot) - BotFather retorna o token - guarde com seguranca
- Comandos uteis do BotFather:
- /setdescription - descricao do bot - /setabouttext - texto "sobre" do bot - /setuserpic - foto de perfil - /setcommands - lista de comandos - /mybots - gerenciar bots existentes - /setinline - habilitar inline mode - /setprivacy - modo privacidade em grupos

app.run_polling()Sem Biblioteca (Http Puro)
import requests
TOKEN = "SEU_TOKEN"
BASE = f"https://api.telegram.org/bot{TOKEN}"
## Verificar Bot
r = requests.get(f"{BASE}/getMe")
print(r.json())
## Enviar Mensagem
r = requests.post(f"{BASE}/sendMessage", json={
"chat_id": "CHAT_ID",
"text": "Hello from pure HTTP!",
"parse_mode": "HTML"
})
print(r.json())Tipos De Mensagem
O Telegram suporta diversos tipos de conteudo. Todos os metodos aceitam chat_id, reply_parameters (para responder), reply_markup (para keyboards), disable_notification e protect_content.
Html (Recomendado)
await bot.send_message(chat_id=chat_id, text="Negrito, italico, codigo, link", parse_mode="HTML")
Markdownv2 (Escapar Caracteres Especiais: _ * [] () ~ ` > # + - = | {}.!)
await bot.send_message(chat_id=chat_id, text="*Negrito*, *italico*, codigo, link", parse_mode="MarkdownV2")
## Foto (Por Url, File_Id Ou Upload)
await bot.send_photo(chat_id, photo="https://example.com/img.jpg", caption="Legenda aqui")
## Documento
await bot.send_document(chat_id, document=open("relatorio.pdf", "rb"), caption="Relatorio mensal")
## Video
await bot.send_video(chat_id, video="https://example.com/video.mp4", caption="Assista!")
## Audio
await bot.send_audio(chat_id, audio=open("musica.mp3", "rb"), title="Minha Musica")
## Voz (Ogg Com Opus)
await bot.send_voice(chat_id, voice=open("audio.ogg", "rb"))
## Localizacao
await bot.send_location(chat_id, latitude=-23.5505, longitude=-46.6333)
## Contato
await bot.send_contact(chat_id, phone_number="+5511999999999", first_name="Joao")
## Enquete
await bot.send_poll(
chat_id, question="Qual sua cor favorita?",
options=["Azul", "Verde", "Vermelho"],
is_anonymous=False
)
## Grupo De Midias
await bot.send_media_group(chat_id, media=[
InputMediaPhoto("url1", caption="Foto 1"),
InputMediaPhoto("url2"),
InputMediaVideo("url3")
])
## Acao De Chat (Typing, Upload_Photo, Etc.)
await bot.send_chat_action(chat_id, action="typing")Node.Js Equivalente
// Foto
bot.sendPhoto(chatId, 'https://example.com/img.jpg', { caption: 'Legenda' });
// Documento
bot.sendDocument(chatId, fs.createReadStream('relatorio.pdf'), { caption: 'Relatorio' });
// Localizacao
bot.sendLocation(chatId, -23.5505, -46.6333);
// Enquete
bot.sendPoll(chatId, 'Qual sua cor favorita?', ['Azul', 'Verde', 'Vermelho']);Inline Keyboard (Botoes Dentro Da Mensagem)
from telegram import InlineKeyboardButton, InlineKeyboardMarkup
keyboard = InlineKeyboardMarkup([
[InlineKeyboardButton("Opcao A", callback_data="opt_a"),
InlineKeyboardButton("Opcao B", callback_data="opt_b")],
[InlineKeyboardButton("Abrir Site", url="https://example.com")],
[InlineKeyboardButton("Compartilhar", switch_inline_query="texto")]
])
await bot.send_message(chat_id, "Escolha uma opcao:", reply_markup=keyboard)
## Handler De Callback
async def button_callback(update: Update, context: ContextTypes.DEFAULT_TYPE):
query = update.callback_query
await query.answer() # Importante: sempre responder o callback
await query.edit_message_text(f"Voce escolheu: {query.data}")
app.add_handler(CallbackQueryHandler(button_callback))Reply Keyboard (Teclado Customizado)
from telegram import ReplyKeyboardMarkup, KeyboardButton
keyboard = ReplyKeyboardMarkup(
[[KeyboardButton("Enviar Localizacao", request_location=True)],
[KeyboardButton("Enviar Contato", request_contact=True)],
["Opcao 1", "Opcao 2"]],
resize_keyboard=True,
one_time_keyboard=True
)
await bot.send_message(chat_id, "Escolha:", reply_markup=keyboard)Remover Teclado
from telegram import ReplyKeyboardRemove
await bot.send_message(chat_id, "Teclado removido", reply_markup=ReplyKeyboardRemove())Receber Updates
Existem duas formas de receber updates: Long Polling e Webhooks.
Long Polling (Desenvolvimento)
Mais simples, ideal para desenvolvimento. O bot faz requisicoes periodicas ao servidor do Telegram.
## Python-Telegram-Bot Ja Faz Isso Automaticamente
app.run_polling(allowed_updates=Update.ALL_TYPES)// node-telegram-bot-api com polling
const bot = new TelegramBot(token, { polling: true });Webhooks (Producao)
Para producao, webhooks sao mais eficientes. O Telegram envia updates via POST para sua URL HTTPS.
Leia references/webhook-setup.md para configuracao completa com Express, Flask, ngrok e deploy.
Setup rapido:
## Flask Webhook
from flask import Flask, request
import requests
app = Flask(__name__)
TOKEN = "SEU_TOKEN"
BASE = f"https://api.telegram.org/bot{TOKEN}"
@app.route(f"/webhook/{TOKEN}", methods=["POST"])
def webhook():
update = request.get_json()
if "message" in update and "text" in update["message"]:
chat_id = update["message"]["chat"]["id"]
text = update["message"]["text"]
requests.post(f"{BASE}/sendMessage", json={
"chat_id": chat_id,
"text": f"Recebi: {text}"
})
return "OK", 200
## Registrar Webhook
requests.post(f"{BASE}/setWebhook", json={
"url": "https://seu-dominio.com/webhook/" + TOKEN,
"allowed_updates": ["message", "callback_query"],
"secret_token": "seu_secret_seguro_aqui"
})Comandos Do Bot
Registre comandos para aparecerem no menu do Telegram:
from telegram import BotCommand
await bot.set_my_commands([
BotCommand("start", "Iniciar o bot"),
BotCommand("help", "Ver comandos disponiveis"),
BotCommand("settings", "Configuracoes"),
BotCommand("status", "Ver status do servico"),
])Via HTTP:
curl -X POST "https://api.telegram.org/bot$TOKEN/setMyCommands" \
-H "Content-Type: application/json" \
-d '{"commands":[{"command":"start","description":"Iniciar o bot"},{"command":"help","description":"Ajuda"}]}'Automacao Com Ia
Padrao para bot de atendimento com IA (Claude, GPT, etc.):
from telegram import Update
from telegram.ext import Application, MessageHandler, filters, ContextTypes
import anthropic # ou openai
client = anthropic.Anthropic()
user_conversations = {} # chat_id -> messages history
async def ai_response(update: Update, context: ContextTypes.DEFAULT_TYPE):
chat_id = update.message.chat_id
user_text = update.message.text
# Indicar que esta digitando
await context.bot.send_chat_action(chat_id, "typing")
# Manter historico
if chat_id not in user_conversations:
user_conversations[chat_id] = []
user_conversations[chat_id].append({"role": "user", "content": user_text})
# Chamar IA
response = client.messages.create(
model="claude-sonnet-4-20250514",
max_tokens=1024,
system="Voce e um assistente prestativo. Responda em portugues.",
messages=user_conversations[chat_id]
)
reply = response.content[0].text
user_conversations[chat_id].append({"role": "assistant", "content": reply})
# Limitar historico (ultimas 20 mensagens)
if len(user_conversations[chat_id]) > 20:
user_conversations[chat_id] = user_conversations[chat_id][-20:]
await update.message.reply_text(reply)
app = Application.builder().token(TOKEN).build()
app.add_handler(MessageHandler(filters.TEXT & ~filters.COMMAND, ai_response))
app.run_polling()Editar Texto
await bot.edit_message_text(chat_id=chat_id, message_id=msg.message_id, text="Texto atualizado!", parse_mode="HTML")
Editar Markup (Botoes)
await bot.edit_message_reply_markup(chat_id=chat_id, message_id=msg.message_id, reply_markup=new_keyboard)
Deletar Mensagem
await bot.delete_message(chat_id=chat_id, message_id=msg.message_id)
Encaminhar Mensagem
await bot.forward_message(chat_id=dest_chat_id, from_chat_id=source_chat_id, message_id=msg.message_id)
---
## Tratamento De Erros
from telegram.error import TelegramError, BadRequest, TimedOut, NetworkError
async def safe_send(bot, chat_id, text, kwargs): """Envio com retry e tratamento de erros.""" max_retries = 3 for attempt in range(max_retries): try: return await bot.send_message(chat_id, text, kwargs) except TimedOut: if attempt < max_retries - 1: await asyncio.sleep(2 attempt) continue raise except BadRequest as e: if "chat not found" in str(e).lower(): print(f"Chat {chat_id} nao encontrado") return None raise except NetworkError: if attempt < max_retries - 1: await asyncio.sleep(2 attempt) continue raise
---
## Rate Limits
- **Mensagens em chat privado:** ~30 msg/segundo
- **Mensagens em grupo:** ~20 msg/minuto por grupo
- **Broadcast geral:** ~30 msg/segundo no total
- **Bulk notifications:** use `asyncio.sleep(0.05)` entre envios para evitar flood
Se receber erro 429 (Too Many Requests), respeite o `retry_after` retornado.
