Description
This automated n8n workflow provides real-time currency conversion by capturing GET requests via a webhook, parsing exchange rate data from Google Search, and returning a formatted response. The system handles query parameter validation and error cases to ensure reliable conversions.
What is Real-Time Currency Conversion?
Real-time currency conversion involves fetching the latest exchange rates from Google Search via HTTP requests, processing the data, and delivering a user-friendly conversion result based on a provided query parameter.
Good to Know
- The workflow requires a valid query parameter (q) for conversion requests
- Google Search parsing depends on the availability and structure of search results
- Error handling is included for missing query parameters
- Responses are formatted for easy integration
How It Works
- Webhook - Captures GET requests with query parameter q
- Check Query Parameter - Validates that the required query parameter exists
- Fetch Exchange Rate - Makes HTTP request to Google search for exchange rates
- Error Response - Handles missing query parameter errors
- Extract Conversion Data - Processes HTML response to extract conversion data
- Format Currency Response - Formats the result into a user-friendly response
- Send Conversion Response - Returns the formatted response
How to Use
- Import the workflow into n8n
- Configure the webhook to receive GET requests with a query parameter (q)
- Test the workflow with sample conversion queries (e.g., “1 USD to INR”)
- Monitor for error responses and adjust query handling if needed
Requirements
- Webhook configuration
- Internet access for Google Search requests
Customizing This Workflow
- Adjust the query parameter validation in the Check Query Parameter node to support additional formats
