How it runs

- Check Query Parameter (If): checks a condition and branches into true / false
- Fetch Exchange Rate (HTTP Request): calls an HTTP API
- Error Response (Respond to Webhook): sends the response back to the webhook caller
- Extract Conversion Data (Code): runs custom JavaScript code
- Format Currency Response (Code): runs custom JavaScript code
- Send Conversion Response (Respond to Webhook): sends the response back to the webhook caller
Before you upgrade to n8n 3.0
