POST /edit

PDF Edit. Stamp, watermark, add headers and footers, set metadata and security on existing PDFs.

Modifies an existing PDF: stamp HTML or text on pages, add watermarks, headers and footers, rotate or delete pages, set metadata, add an outline, encrypt with passwords and permissions, or add a digital signature. Send the PDF as an upload and the edits as a JSON operations array.

Authentication, rate limits, versioning and the error format are shared by every operation — see the API reference index and the error codes. One credit per successful request on the hosted API.
