APITemplate.io — Automate PDF Documents and Images at Scale

APITemplate.io is a platform that lets you auto-generate PDF documents and images at scale. Whether you need invoices, reports, certificates, social media graphics, or banners, you can create reusable templates and generate files through a simple API call or no-code integrations.

What can you do with it?​

  • Generate PDFs from reusable HTML templates, a visual WYSIWYG editor, or directly from a URL
  • Generate images like social media posts, banners, open graph images, and infographics using a a WYSIWYG editor similar to Microsoft Word
  • Automate workflows with Zapier, Make.com, n8n, Airtable, Bubble.io, or the REST API
  • Use dynamic data by passing JSON to your templates — swap out text, images, dates, and more on every request
  • Scale reliably with regional API endpoints (US, EU, Singapore, Australia), sync/async generation, and webhooks

How it works​

The workflow is straightforward:

  1. Design a template — Use HTML/CSS or the visual editor to create a reusable layout
  2. Send data — Pass JSON through the REST API, Zapier, Make.com, or another integration
  3. Get your file — Receive a download URL for the generated PDF or image
