Automate Euro Exchange Rate Retrieval and Filtering with n8n
detail.loadingPreview
This n8n workflow automates the retrieval of daily Euro foreign exchange rates from the European Central Bank. It handles XML data, allows for selective filtering based on currency queries, and provides flexible response options for integration into other systems.
About This Workflow
This n8n workflow is designed to efficiently fetch and process real-time Euro foreign exchange rates. It begins with an incoming webhook trigger, followed by an HTTP request to the European Central Bank's daily exchange rate XML feed. To ensure the freshest data, a randomized URL parameter is appended to bypass caching. The raw XML data is then expertly converted into a JSON format for easier manipulation. Subsequently, the data is split into individual currency records, enabling granular control. A conditional logic branch checks for specific currency queries passed via the webhook's URL. If a query exists, the workflow filters the rates to match the requested currency, and the specific result is sent back via webhook response. If no query is present, all retrieved exchange rates are returned. This workflow is ideal for applications requiring up-to-date currency data for financial analysis, trading platforms, or international transaction processing.
Key Features
- Real-time Data Fetching: Automatically retrieves the latest daily Euro exchange rates.
- Robust Data Handling: Seamlessly converts XML data to a usable JSON format.
- Intelligent Filtering: Allows users to query and receive specific exchange rates via webhook parameters.
- Flexible Response Options: Can respond with individual filtered rates or all retrieved rates.
- Cache Busting: Implements a strategy to ensure the most current data is always fetched.
How To Use
- Set up the Webhook Trigger: Configure the
Incoming Webhook Triggernode with a unique path (e.g.,eu-exchange-rate). EnsureresponseModeis set toresponseNode. - Fetch Exchange Rates: The
Get latest Euro exchange ratesnode is pre-configured to fetch data from the ECB. The randomized URL parameter helps avoid caching. - Convert XML to JSON: The
Convert XML to JSONnode will automatically transform the fetched XML into a JSON structure. - Split Data: Use the
Split Out Datanode to break down the JSON into individual currency entries. - Implement Conditional Logic: The
If Webhook Trigger has URL querynode checks if a query parameter is present in the incoming webhook. - Filter Specific Currencies (if query exists): If a query is detected, the
Filter the currency symbolnode uses thequery.foreignparameter to find the matching currency rate. - Respond to Webhook: Connect the output of the
Filter the currency symbolnode to theRespond Asked Itemnode to return the specific rate. If no query was detected, connect the output of theIf Webhook Trigger has URL querynode's false branch to theRespond All Itemsnode to return all rates.
