Generate PDF documents from HTML with PDF Generator API, Gmail and Supabase
Streamline your document production by converting HTML templates into professional PDFs automatically whenever a webhook is triggered. This robust workflow ensures data integrity with email verification before delivering documents via Gmail and securely archiving them in Supabase. It's the perfect solution for businesses needing automated, high-quality invoices or certificates delivered instantly to clients.
Start BuildingWhat This Recipe Does
This automation streamlines the entire document generation lifecycle, transforming raw data into professional PDF documents without manual intervention. By connecting your database and communication tools directly to a high-fidelity PDF generator, this workflow eliminates the tedious task of manual data entry and template formatting. When a request is triggered, the system automatically retrieves necessary information from Supabase or Postgres, validates contact details via Hunter, and generates a custom HTML-based document. Once the document is created, the system handles the distribution by sending it directly to the recipient via Gmail and archiving the record for future reference. This ensures that contracts, invoices, or reports are delivered instantly and accurately, allowing your team to focus on high-value tasks rather than administrative paperwork. It provides a scalable solution for businesses that need to maintain consistent branding and high volume document output while minimizing human error.

Frequently Asked Questions
Do I need to know how to code to change the document design?
While the system uses HTML templates for maximum flexibility, you can use any standard HTML editor to design your layout, or use pre-made templates provided by the PDF Generator API.
Can I use a different email provider instead of Gmail?
Yes, the workflow is modular and can be easily adjusted to send emails through Outlook, SendGrid, or any other preferred communication platform.
How does the system handle missing or incorrect email addresses?
The integration with Hunter automatically verifies email data before transmission, ensuring your documents reach the intended recipient and protecting your sender reputation.
Where are the generated documents stored?
Every generated document is tracked within your connected database (Supabase or Postgres), providing a permanent audit trail of what was sent and to whom.
