How to do it

the tool · the steps · what to avoid

1
Set up a dedicated folder in your cloud storage (such as OneDrive, SharePoint, or Google Drive) to receive incoming PDFs that require sanitization.
2
Create a new workflow in Power Automate or Zapier that triggers when a new PDF file is added to this folder.

Configure the external service or script to use the Adobe PDF Services API’s Remove PDF Elements operation, selecting options to remove hidden data, metadata, and other sensitive content.
CautionEnsure your API credentials and permissions are securely managed when integrating with Adobe PDF Services API.
5
Set the workflow to save the sanitized PDF to a designated output folder or send it to the next step in your business process.
