How to Schedule Telegram Messages

Dynamic Content Scheduling

Render messages from live data, APIs or user context.

• • Weather-based messages
• • Personalized user data
• • Real-time statistics
• • API-driven content

Conditional Scheduling

Send messages only when conditions match.

• • User activity triggers
• • Time-based conditions
• • Event-driven messages
• • A/B testing scenarios

Multi-Platform Synchronization

Coordinate Telegram with email, SMS, or other socials.

• • Cross-platform campaigns
• • Unified scheduling dashboard
• • Message consistency
• • Centralized analytics

Smart Retry Logic

Recover gracefully from failures.

• • Exponential backoff
• • Rate limit handling
• • Error categorization
• • Failure notifications

✅ Do's

• ✓ Respect rate limits; add throttling
• ✓ Segment audiences & schedule per timezone
• ✓ Implement retries & idempotency keys
• ✓ Log deliveries and failures
• ✓ Use environment variables for tokens

❌ Don'ts

• ✗ Spam or message without consent
• ✗ Hardcode bot tokens in code
• ✗ Ignore 429 Too Many Requests errors
• ✗ Send during local off-hours without reason
• ✗ Log sensitive PII or tokens

Node.js (node-cron) Örneği

import cron from 'node-cron';
import fetch from 'node-fetch';

const BOT = process.env.BOT_TOKEN!;
const CHAT = process.env.CHAT_ID!;

cron.schedule('0 9 * * 1-5', async () => {
  const msg = encodeURIComponent('Günaydın! ☕️');
  await fetch(`https://api.telegram.org/bot${BOT}/sendMessage?chat_id=${CHAT}&text=${msg}`);
});

Python (schedule) Örneği

import time, requests, os, schedule

BOT = os.environ["BOT_TOKEN"]
CHAT = os.environ["CHAT_ID"]

def send():
    requests.post(f"https://api.telegram.org/bot{BOT}/sendMessage", data={"chat_id": CHAT, "text": "Weekly report ready 📊"})

schedule.every().monday.at("09:00").do(send)

while True:
    schedule.run_pending()
    time.sleep(1)
