Summary

Add attachments as image overlays to an existing PDF file or binary file input, optionally converting the result to PDF/A-3b format.

Inputs

  • fileInputBinaryProperty — Name of the binary property containing the existing PDF file data to which the attachments will be added.
  • fileId — File ID referencing a server-side PDF file to which the attachments will be added; can be used instead of providing file data.
  • attachmentsBinaryProperty (required) — Name of the binary property containing the image files to overlay onto the PDF as attachments.
  • convertToPdfA3b — Boolean flag to convert the resulting PDF to PDF/A-3b format after attachments are added.

Output shape

a single binary PDF file with the attachments added

The output is a PDF file with the added attachment overlays; if convertToPdfA3b is set, the PDF complies with PDF/A-3b standard. Input can be a binary file or a server-side file id. Request options like batching, timeout, proxy, and SSL settings affect the operation but are advanced settings.
