Who is this template for?

This workflow is designed for crypto analysts, finance teams, or automation enthusiasts who want to collect and track crypto exchange rates automatically for reporting or analysis.

Let’s imagine you want to monitor BTC and ETH prices against the EUR:

The Alpha Vantage API is called every hour to collect the exchange rate, bid/ask prices, and timestamp.

This data is saved in Google Sheets and can trigger a Telegram alert.

How does it work?

This workflow automates the hourly logging of crypto exchange rates:

⏰ Schedule Trigger launches the workflow every hour
🌐 Alpha Vantage API fetches BTC and ETH exchange rates (to EUR)
📄 Google Sheets node appends each result to a tab (BTC or ETH)
📲 Telegram node sends a summary alert with the latest rate info

Steps:

⏰ Trigger every hour via Schedule node
🌐 Call Alpha Vantage API for BTC and ETH
📊 Append rates, bid/ask prices, and timestamp to Google Sheets
📲 Send formatted Telegram message with rate summary

What do I need to get started?

You’ll need:

A free Alpha Vantage API key
A Google Sheet with BTC and ETH tabs
A Telegram bot and Chat ID to send notifications
