Automate Crypto Updates: Telegram Alerts with CoinGecko API

Never miss a crypto market move again! This powerful n8n workflow automatically tracks cryptocurrency prices using the CoinGecko API and delivers beautifully formatted price updates directly to your Telegram channel or group every hour.

What this workflow does

This automation runs on a customizable schedule (default: hourly) to monitor your selected cryptocurrency portfolio. The workflow fetches real-time market data including current prices and percentage changes from CoinGecko's public API, then aggregates individual coin data into a comprehensive dataset. A JavaScript transformation node converts the raw market data into a clean, HTML-formatted report that's automatically pushed to your designated Telegram destination.

Use cases

• Portfolio monitoring: Track your crypto investments with regular automated updates
• Team notifications: Keep trading teams informed with scheduled market summaries
• Community channels: Provide valuable price alerts to cryptocurrency community groups
• Personal alerts: Stay updated on market movements without constantly checking exchanges
• Research automation: Monitor specific altcoins or market segments for analysis purposes

Technical details

Built with essential n8n nodes including Schedule Trigger for automated execution, CoinGecko node for cryptocurrency data retrieval, Code node for data transformation, Aggregate node for data processing, and Telegram node for message delivery. The workflow requires minimal setup - just a Telegram bot token from BotFather and your target chat ID.

Customization is straightforward: modify the tracked cryptocurrency list in the 'Define Coins' node using CoinGecko slugs, adjust the schedule trigger interval, or customize the message formatting including emojis, currency display, and language in the 'Generate Telegram Message' node. No CoinGecko credentials needed thanks to their public API access.
