HTTP Request sends its binary content to Repondea Invoice CSV. The service returns eight suggested fields, warnings, page usage and requires_review: true. A final Edit Fields node marks the result for human review and records the original filename. There is no automatic accounting entry or export.\n\n## Setup\n1. Create a Repondea account and confirm your email. Five pages per calendar month are free, with no card; Pro is optional at EUR 9/month for 50 pages.\n2. Create a revocable key in your workspace. Add an n8n Header Auth credential: Name = Authorization; Value = Bearer followed by a space and the key.\n3. Attach that credential to Extract invoice fields. Run the workflow and open the form test URL.\n4. Upload one readable invoice (maximum 5 MB and three PDF pages). Download the final JSON result, select the original in the Repondea workspace, and load that JSON for review. Correct fields and confirm before CSV export.\n\n## Requirements and customization\nAn n8n instance and Repondea account. Native nodes only; no model API key. Your n8n execution history may store documents and results: configure its retention. Keep human review when adding downstream integrations.\n\n[Full guide](https://repondea.com/en/invoice-csv/n8n?source=n8n-invoice-csv)",
