]);Questions, answered.
Can't find what you need? Email an@bannerify.co and you'll hear back from the founder.
Can I use the same template for a PDF and an image?
Yes. Every template can render as a PDF or as a PNG, JPEG, or WebP image. Pick the endpoint that matches the file you need.
How do I add a table to a PDF?
Add a table layer in the editor and style it. Then send columns and rows in the modifications for that layer. The styling stays the same, only the data changes.
Can I get a link instead of the file?
Yes. createStoredPdf stores the file and returns a hosted URL. On Business and Enterprise you can store files in your own S3 or R2 bucket.
Can I generate PDFs without code?
Yes. The Zapier and n8n integrations include a Render PDF action, so you can create a PDF from a form, spreadsheet row, or order.
Your first PDF is a few minutes away.
Design an invoice or label once, then generate every copy from your data.
