Hey Product Hunt 👋 I’m the maker of DocuHook — a small API that turns webhook JSON + an HTML template into a PDF. The problem Most “webhook → invoice/PDF” flows end up running Puppeteer/Chromium in a serverless function. Cold starts, timeouts, and held-open HTTP connections during bursts make that painful. What DocuHook does POST data + html → merged HTML / PDF Sync for interactive calls Async (202 + job) when webhooks pile up Live sandbox on the homepage — no signup Lightweight WordPress plugin if you’re on WooCommerce / WP Try the sandbox: docuhook.com → Open live sandbox Would love feedback from anyone who’s fought PDF generation in webhooks or serverless. What would you want next — email/S3 delivery, more template helpers, or tighter Zapier/Make support?
