Building a Bitcoin Price Notification Service with Python and IFTTT

·

Monitoring cryptocurrency prices in real time can be essential for traders, investors, and tech enthusiasts alike. With Bitcoin’s volatile nature, staying updated on price movements is more than just convenient—it can be profitable. In this guide, you’ll learn how to build a Bitcoin price notification service using Python, leveraging the CoinMarketCap API and IFTTT webhooks to receive timely alerts on your phone or email.

This project is perfect for beginners diving into automation, APIs, and real-world Python applications. By the end, you’ll have a fully functional system that checks Bitcoin’s price at regular intervals and notifies you when key thresholds are met.

Why Build a Bitcoin Price Alert System?

Automated price tracking removes the need for constant manual monitoring. Whether you're watching for a dip to buy or a surge to sell, timely alerts empower smarter decisions. This system combines three powerful tools:

Step 1: Set Up Your Development Environment

Before writing any code, ensure Python is installed on your machine. Most modern systems support Python 3.6+, which is ideal for this project.

Install the required packages using pip:

pip install requests

The requests library simplifies sending HTTP requests—essential for interacting with both CoinMarketCap and IFTTT.

Step 2: Access Real-Time Bitcoin Data with CoinMarketCap API

CoinMarketCap offers a free API tier that provides real-time cryptocurrency pricing data.

How to Get Your API Key

  1. Visit coinmarketcap.com and sign up.
  2. Navigate to the "API" section and create a new API key.
  3. Copy the key—you'll use it to authenticate requests.

Once you have your key, you can query Bitcoin’s current price using a simple GET request:

import requests

url = "https://pro-api.coinmarketcap.com/v1/cryptocurrency/quotes/latest"
headers = {
    "X-CMC_PRO_API_KEY": "your_api_key_here"
}
params = {
    "symbol": "BTC",
    "convert": "USD"
}

response = requests.get(url, headers=headers, params=params)
data = response.json()

btc_price = data['data']['BTC']['quote']['USD']['price']
print(f"Current Bitcoin price: ${btc_price:,.2f}")

This script retrieves Bitcoin’s latest USD price from the CoinMarketCap API in JSON format.

Step 3: Set Up IFTTT Webhooks for Instant Notifications

IFTTT allows you to automate actions across apps and devices. We’ll use its Webhooks service to trigger notifications from our Python script.

Create an IFTTT Account

Go to ifttt.com and sign up for a free account.

Create a Test Applet

  1. Click Create > New Applet.
  2. For the trigger, search for Webhooks > Receive a web request.
  3. Name the event: test_notification.
  4. For the action, choose Notifications > Send a notification.
  5. Enter message: Test Notification Received.
  6. Save the applet.

You now have a webhook URL template:

https://maker.ifttt.com/trigger/{event}/with/key/{your_key}

Replace {event} with your event name (e.g., test_notification) and {your_key} with your personal IFTTT key found under Webhooks settings.

Test it by visiting the full URL in your browser—you should receive a notification instantly.

Step 4: Build IFTTT Applets for Price Alerts

Now create two useful applets:

1. Emergency Alert: Price Drop Warning

We’ll implement the logic in Python later.

2. Regular Update: Hourly Price Summary

Use IFTTT’s Date & Time service as the trigger and repeat every 60 minutes.

Step 5: Implement the Core Python Script

Now bring everything together with a script that:

import requests
import time

# Configuration
CMC_API_KEY = "your_coinmarketcap_api_key"
IFTTT_KEY = "your_ifttt_webhook_key"
ALERT_THRESHOLD = 50000  # USD
CHECK_INTERVAL = 600     # Seconds (10 minutes)

def get_bitcoin_price():
    url = "https://pro-api.coinmarketcap.com/v1/cryptocurrency/quotes/latest"
    headers = {"X-CMC_PRO_API_KEY": CMC_API_KEY}
    params = {"symbol": "BTC", "convert": "USD"}
    
    response = requests.get(url, headers=headers, params=params)
    data = response.json()
    return data['data']['BTC']['quote']['USD']['price']

def send_ifttt_notification(event_name, value=None):
    url = f"https://maker.ifttt.com/trigger/{event_name}/with/key/{IFTTT_KEY}"
    payload = {"value1": value} if value else {}
    requests.post(url, json=payload)

# Main loop
previous_price = None
while True:
    try:
        current_price = get_bitcoin_price()
        print(f"Bitcoin Price: ${current_price:,.2f}")
        
        # Send alert if price drops below threshold
        if current_price < ALERT_THRESHOLD:
            send_ifttt_notification("btc_alert", f"⚠️ BTC dropped to ${current_price:,.2f}!")
        
        # Send update if price changed significantly
        if previous_price:
            change_percent = abs((current_price - previous_price) / previous_price) * 100
            if change_percent > 2:  # 2% change
                trend = "↑" if current_price > previous_price else "↓"
                send_ifttt_notification("btc_update", f"Bitcoin {trend} ${current_price:,.2f} ({change_percent:.1f}% change)")
        
        previous_price = current_price
    
    except Exception as e:
        print(f"Error: {e}")
    
    time.sleep(CHECK_INTERVAL)

This script runs continuously, checking the price every 10 minutes and triggering notifications based on conditions.

Step 6: Enhance with HTML Formatting (Optional)

You can extend this system to send formatted updates to platforms like Telegram by using HTML or Markdown in your payload. For example:

message = f"""
<b>Bitcoin Update</b>
📅 Date: {time.strftime('%Y-%m-%d')}
🕐 Time: {time.strftime('%H:%M')}
💰 Price: ${current_price:,.2f}
📊 Trend: {trend_message}
"""

IFTTT can forward this to Telegram bots or email with rich formatting enabled.
