Automated PDF Form Filling for W-9 and More with PDF.co — n8n Workflow

Low complexity⚡ Trigger3 nodes💎 Otherby Robert Breen

Overview

🧑‍💻 Description This workflow demonstrates how to take structured data (e.g., Name, Business, Address) and automatically fill a PDF form (IRS W-9) using PDF.co inside n8n.

The workflow extracts values from a data source (e.g., Set node, database, or webhook), maps those values to fields in a PDF template, and generates a completed PDF. This can be adapted for contracts, invoices, HR forms, or any standardized documents that need automation.

By chaining additional nodes, you can also store
