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
