Real-Time Currency Conversion via Webhook & Google Search Parsing

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
• Modify the Format Currency Response node to change the output format based on user needs
