💰 Track Daily Fiat & Crypto Exchange Rates Report with ExchangeRate-API & CoinGecko
💰 Track Daily Fiat & Crypto Exchange Rates Report with ExchangeRate-API & CoinGecko A simple, reliable workflow that emails you a beautiful HTML currency report every morning at 8:00 AM (your n8n server’s timezone). It pulls USD→EUR and USD→NGN fiat rates and BTC/ETH prices (+ 24h % change), then formats a clean HTML email. 📌 What It Does ⏰ Schedule: Runs daily at 8:00 AM 🌍 Fiat Rates: USD→EUR and USD→NGN (via ExchangeRate-API, no key needed) ₿ Crypto: BTC & ETH prices + 24h change (via CoinGecko, no key needed) ✉️ Email: Sends a mobile-friendly HTML + plain text fallback 🗺️ Node Map (At a Glance) | # | Node Name | Type | Purpose | |---|-----------|------|---------| | 1 | Daily 8AM Trigger | Schedule Trigger | Fires every day at 08:00 | | 2 | Get Fiat Exchange Rates | HTTP Request | https://api.exchangerate-api.com/v4/latest/USD | | 3 | Get Crypto Prices | HTTP Request | CoinGecko simple price endpoint | | 4 | Merge | Merge | Combines fiat + crypto responses | | 5 | Format Email Content | Code (v2) | Builds HTML + text, sets subject & summary | | 6 | Send Daily Currency Email | Email Send | Sends the HTML email via SMTP | > 📝 Sticky Notes in the canvas explain each section. They’re optional and safe to delete. ⚙️ Required Setup 1) Schedule Time Open Daily 8AM Trigger → set cron to 08:00 daily. Suggested cron: 0 8 * * (server local time; if you’re in Lagos, ensure server timezone matches *Africa/Lagos** or adjust accordingly). 2) SMTP Credentials Open Send Daily Currency Email → set: From Email: your sender (e.g. your-email@gmail.com) To Email: recipient address Credentials: select your SMTP account Gmail tip:* use *App Passwords** (with 2FA enabled). Server: smtp.gmail.com Port: 587 (STARTTLS) or 465 (SSL) Auth: your full Gmail address + app password 3) API Access Both endpoints are free & no API key: Fiat (USD base): https://api.exchangerate-api.com/v4/latest/USD Crypto (BTC/ETH): https://api.coingecko.com/api/v3/simple/price?ids=bitcoin,ethereum&vs_currencies=usd&include_24hr_change=true 🧩 Input Order The Format Email Content node is written to auto-detect which input is fiat vs crypto, so the Merge order doesn’t matter. A clean pattern is: Get Crypto Prices* → *Merge** (Input 1) Get Fiat Exchange Rates* → *Merge** (Input 2) Merge* → *Format Email Content* → *Send Daily Currency Email** 🚀 Test It Quickly Run Get Fiat Exchange Rates → verify rates.EUR and rates.NGN exist. Run Get Crypto Prices → verify BTC/ETH usd and usd_24h_change. Run Format Email Content → check it outputs subject, html, text. Run Send Daily Currency Email → confirm the styled report arrives. 🎛 Customize Currencies:** Add more fiat codes from rates (e.g., GBP, ZAR) and extend the HTML template. Coins:** Add ids= in CoinGecko (e.g., bitcoin,ethereum,solana) and render extra cards. Send time:** Adjust the cron (e.g., 30 7 * * * for 7:30 AM). Branding:** Edit colors, fonts, and header gradient in the HTML string. Timezone stamp:** Change the display timezone inside the Code node if needed. 🧩 Common Pitfalls & Fixes Email not styled:* Ensure the Email node is set to *HTML** format. Gmail auth fails:* Use an *App Password* and port *587** with STARTTLS. Empty values:** Run the two HTTP nodes once and confirm the responses contain data. Rate limits:** If you increase frequency, consider adding a short Wait node or caching. An n8n automation workflow template by David Olusola.
