Add Water mark in PDF

[Rafael Batistot]

Hi team,

I'm working on a Service Portal process where users can upload and download attachments. I need to implement a way to automatically add a watermark to these PDF files before they are downloaded.

The workflow is: A user uploads an external PDF from their computer. When any user later downloads that same file from the portal, the downloaded version should contain the watermark.

I’ve already tried using PDFGeneratorAPI, but it didn't meet the requirements. Does anyone have experience with a similar use case or suggestions for a different approach?

any PDF attached in platform can't be manipulated with data as OOTB there is nothing to read the pages etc and hence can't add watermark

you will have to rely on some external API etc and build a custom solution for this

Thank you for your reply. I was wondering if you have any recommendations for an external API I could use?
