Who is this workflow for? Streamline your currency conversion processes with this n8n workflow. Automate real-time currency exchanges by handling HTTP requests through a webhook, fetching up-to-date exchange rates from Google, and delivering accurate conversion results without relying on external APIs..

What does this workflow do?

  • Capture Conversion Query:
  • The workflow starts by receiving a GET request via a configured webhook.
  • Users input conversion queries in a structured format, such as 5usd to mxn.
  • Testing Tip: Utilize tools like Postman or a web browser to send GET requests and ensure the webhook correctly receives the input.
  • Fetch Exchange Rate:
  • An HTTP Request node sends a Google search query to obtain the latest exchange rate.
  • This method maintains cost-effectiveness and flexibility by avoiding API dependencies.
  • Extract Conversion Data:
  • Processes the HTML response from Google to isolate the current exchange rate and relevant contextual information.
  • Error Handling: If data extraction fails, verify input syntax and update CSS selectors to match any changes in Google’s HTML structure.
  • Format Currency Response:
  • Refines the extracted data into a clear, structured string that presents the conversion result succinctly.
  • Send Conversion Response:
  • Sends the formatted conversion result back to the origin of the request, completing the automated loop efficiently.
