• pdfUrl (required) — When the PDF source is a URL, the PDF URL.
• outputFileName — Output PDF filename; defaults to document_with_image_stamp.pdf.
• docName — Source PDF filename for reference; defaults to document.pdf.

Output shape

A PDF document returned as binary data.

The operation fields are declared in the supplied properties, but the source pack only shows the action function signature, not its implementation. Output behavior and how size and margin settings interact cannot be confirmed from the supplied source.
