Bitcoin Price Alert to Telegram via CoinPaprika

🚀 Overview

This workflow monitors Bitcoin price movements using the free, keyless CoinPaprika API and sends instant alerts to your Telegram when the price changes by 5% or more in the last 24 hours. It's a practical, no-cost solution for staying on top of crypto volatility without needing any API keys or paid subscriptions.

🔧 Workflow Nodes

Below is a step‑by‑step breakdown of every node in the workflow:

1. Every 15 minutes (Schedule Trigger — No auth)
   Runs the workflow automatically every 15 minutes using n8n’s built-in scheduler. You can adjust the interval in the node settings (e.g., change to every hour).

2. Get BTC price (CoinPaprika) (HTTP Request — No auth)
   Fetches the latest Bitcoin ticker data from CoinPaprika’s public endpoint https://api.coinpaprika.com/v1/tickers/btc-bitcoin. No authentication is required. The response includes current price, 24h change, 7d change, and more.

3. Big 24h move? (IF — No auth)
   Evaluates two conditions using an OR combinator:

   • quotes.USD.percent_change_24h >= 5 (price up 5% or more)
   • quotes.USD.percent_change_24h <= -5 (price down 5% or more)
     If either condition is true, the workflow proceeds to the Telegram node; otherwise it stops.

4. Send Telegram alert (Telegram — Telegram Bot API auth)
   Sends a formatted message to a specific Telegram chat using a bot. The message includes:

   • Current price (formatted to 2 decimals)
   • 24h change percentage
   • 7d change percentage
     You must replace YOUR_TELEGRAM_CHAT_ID with your actual chat ID and configure a Telegram credential in n8n (Bot Token).

📋 Setup Instructions

1. CoinPaprika – No signup or API key needed. The public endpoint works out of the box.
2. Telegram – You need a Telegram bot:
   • Create a bot via @BotFather and get its token.
   • Find your chat ID (or group ID) where alerts should be sent.
   • In n8n, add a new Telegram credential with the bot token, then paste it into the Send Telegram alert node.
   • Replace the placeholder YOUR_TELEGRAM_CHAT_ID with your actual ID.
3. n8n – Import this workflow, configure the Telegram credential, and activate it.

💡 Use Cases & Variations

• Track other coins: Change the URL from btc-bitcoin to any CoinPaprika ticker ID (e.g., eth-ethereum, sol-solana).
• Adjust threshold: Modify the 5% values in the Big 24h move? node to any percentage (e.g., 2% for smaller moves).
• Add more conditions: Combine with additional metrics like volume spikes or market cap changes.
• Send to different channels: Replace Telegram with Slack, Email, or a custom webhook by swapping the last node.
• Log data: Insert a Google Sheets node before the IF node to record price data over time.

This workflow is ideal for crypto traders, hobbyists, or anyone who wants real‑time price alerts without paying for premium services.
