Automate invoices, payments, and refunds
An n8n workflow manages invoices, payments, and refunds, updating records with status, PDF links, and timestamps. Task: Suggested implementation: Build an n8n workflow triggered by a webhook with API-key validation. Route invoice, payment, and refund events separately. Use Google Sheets for records, PDFbro for PDF generation, Google Drive for storage, and Resend for emails. Include duplicate checks before processing. Human role: Review workflow logic and approve test outputs before production deployment.; tools: n8n. Human role: The original post does not say how a person stayed involved.; limitations: Prerequisites: Access to n8n, Google Sheets, PDFbro, Google Drive, and Resend APIs. Constraints: Requires robust state management and duplicate detection logic, not just app connections. Integration uncertainty: API rate limits and authentication failures may occur.

Overview
An n8n workflow manages invoices, payments, and refunds, updating records with status, PDF links, and timestamps.
Workflow
Suggested implementation: Build an n8n workflow triggered by a webhook with API-key validation. Route invoice, payment, and refund events separately. Use Google Sheets for records, PDFbro for PDF generation, Google Drive for storage, and Resend for emails. Include duplicate checks before processing. Human role: Review workflow logic and approve test outputs before production deployment.
Reported result
Actual outcomes are unknown as the source is inaccessible. Proposed acceptance check: Verify that duplicate events do not create redundant records or send multiple emails. Monitor error rates in webhook triggers and API responses. Confirm that generated PDFs are correctly stored and linked in Google Sheets.
Human role

Limitations
Prerequisites: Access to n8n, Google Sheets, PDFbro, Google Drive, and Resend APIs. Constraints: Requires robust state management and duplicate detection logic, not just app connections. Integration uncertainty: API rate limits and authentication failures may occur. Source reliability: Low, as the original post is unavailable (HTTP 403).

Try it
Act as an automation engineer. I need to build an n8n workflow to handle invoices, payments, and refunds. Inputs: [Replaceable: Webhook URL, API Key, Google Sheet ID, PDFbro API Key, Google Drive Folder ID, Resend API Key]. Steps: 1. Create a webhook trigger with API-key validation. 2. Set up conditional routing for 'invoice', 'payment', and 'refund' events. 3. For each route, implement a duplicate check against [Replaceable: Google Sheet ID]. 4. If unique, generate PDF using PDFbro, store in Google Drive, and send email via Resend. 5. Update Google Sheet with status, PDF link, and timestamp. Deliverables: A JSON export of the n8n workflow and a test log. Quality Check: Run a dry run with 3 sample events (1 duplicate, 2 unique). Verify no duplicate emails or records are created. Safeguards: Do not connect to live production data. Use test accounts. Require my explicit confirmation before enabling the workflow for real transactions. If any API key is missing, ask me for it before proceeding.
