uProc Finance Operations Automation

This n8n workflow automates uProc financial operations, processing credit card, banking, currency, and VAT data via the uProc API. Key nodes include Webhook Trigger (receives POST requests), Extract Request Metadata (captures client data), uProc Finance Rate Limit Check, Validate and Sanitize Input, Credit Card/Bank/Currency/VAT Operations (API interactions), Mask Sensitive Data, and Success/Error Response nodes (handle outputs). Set up Requirements and Configuration: Install n8n by downloading from n8n.io for self-hosting or sign up at cloud.n8n.io for cloud setup. Follow installation prompts or create a cloud account. Obtain uProc API credentials from app.uproc.io: log in, go to 'Profile' > 'API,' and copy your API Key. In n8n, import the provided JSON to create the workflow. Configure uProc nodes (Credit Card/Bank/Currency/VAT Operations) with your API Key under 'Credentials,' selecting 'uProc API.' Set the Webhook Trigger node’s path to 'uproc/finance,' enable header authentication with a secure key, and ensure it accepts POST requests. The Validate and Sanitize Input node checks tool, creditCard, iban, currency, and GDPR consent. Testing and Deployment Steps: Test by sending a POST request to the Webhook URL (from the Webhook Trigger node) using Postman. Example JSON body: {'tool': 'checkcreditcardchecksum', 'creditCard': '4532015112830366', 'pciCompliant': true, 'financialCompliance': true, 'businessPurpose': 'payment validation', 'gdprConsent': true} or {'tool': 'getcurrencyconvertedbetweenisocodedate', 'currency1': 'USD', 'currency2': 'EUR', 'amount': 100, 'date': '2025-07-26'} with the authentication header. The 'Finance Success Response' node returns a 200 status with masked results, or 'Validation Error Response' (400 status) for invalid inputs like incorrect credit cards or IBANs. The 'Rate Limit Response' (429 status) triggers if exceeding 5 requests per minute. The 'Invalid Data Response' (422 status) or 'Finance API Error Response' (500 status) indicates API issues. Activate the workflow in n8n’s interface for deployment. Monitor logs for errors like invalid API keys or missing PCI compliance, and verify credentials or input formats if issues occur.
