Daily Currency Exchange Rate Updates via CurrencyFreaks API & Gmail

This n8n workflow automates the daily retrieval and distribution of currency exchange rates, ensuring users stay updated without manual checks. It starts with a configurable Schedule Trigger that runs at set intervals (e.g., daily). Variables are set for the CurrencyFreaks API key and preferred currencies like PKR, GBP, EUR, USD, BDT, and INR. An HTTP Request node fetches the latest rates from the API using these parameters.

Next, nodes prepare the email by setting the recipient address and a dynamic subject line incorporating the current date. The Gmail node, authenticated via OAuth2, sends a professional HTML-formatted email with the rates data, base currency, and timestamp. This streamlined flow eliminates repetitive tasks, reduces errors, and provides real-time financial insights.

Benefits include time savings for traders, businesses, or individuals monitoring multiple currencies, especially in volatile markets. Use cases span financial reporting, international business operations, travel budgeting, or e-commerce pricing adjustments. Highly customizable for different currencies, frequencies, or email templates, it integrates seamlessly into BI dashboards or alerts systems.
