How to merge password-protected PDFs
We plan to add the password removal feature in the next PDF Merger API update.
For now, please use the PDF Security API v1/pdf/security/remove endpoint to remove the PDF password and pass this PDF into the PDF Merger API.
You can also re-add the password protection using the v1/pdf/security/add endpoint.
