Automated Invoice PDF Generation via Webhook

This workflow automates the generation of a professional invoice PDF from incoming webhook data. When a webhook triggers the process, predefined invoice details, billing information, and itemized charges are processed and formatted into an HTML invoice template. The workflow then converts this HTML into a PDF using a custom JavaScript node. Finally, it responds to the webhook, completing the automation. This setup is useful for businesses needing instant, on-demand invoice creation—such as after a sale or service request—delivering neatly formatted PDFs seamlessly. The entire process involves a webhook trigger, data preprocessing, HTML template rendering, PDF conversion, and webhook response, integrating n8n nodes and custom code for seamless execution.
