API Playground
Generate a real watermarked PDF without an API key
Use the public sandbox to test the same server-side PDF engine used by the Business API. No account or API key is required.
Edit the fields, then generate the server-side PDF.
curl -X POST https://sheetstolabels.com/api/v1/demo/generate-pdf \
-H "Content-Type: application/json" \
-d '{"name":"Alex Morgan","title":"Community Ambassador","company":"Northstar Events","qrUrl":"https://sheetstolabels.com"}' \
--output api-demo.pdfThe playground uses a fixed one-page template and adds a visible demo watermark. It accepts text and a QR code URL only; it does not load external images or access your saved templates. Each visitor can make up to 3 requests per minute and 10 requests per day.
To test your own cloud template and the authenticated workflow, sign in and start the one-time 7-day API trial from API Key Settings. The trial includes 10 successful single-page requests and does not consume Credits.
When you are ready to integrate, continue with the API Quick Start.
