n8n

PDF Redaction is available as an official n8n community node, @stabrise/n8n-nodes-pdf-redaction. It lets you redact PII in PDFs as a step in any n8n workflow — no custom REST integration code required.

View on npm

Source code is available on GitHub.

Installation

Install the node like any other n8n community node:

1. In n8n, go to Settings → Community Nodes → Install.
2. Enter the package name @stabrise/n8n-nodes-pdf-redaction.
3. Confirm the installation.

Requires n8n version 1.60.0 or later.

Authentication

1. Generate an API key at https://pdf-redaction.com/apikeys/.
2. In n8n, create a new PDF Redaction API credential and paste in your API key.

Requests made from the node run against your account's usage and credits, the same as the REST API.

Available operations

The node exposes three operations. Input PDFs are read from a binary property; redacted PDFs and detected PII are returned in the output, as binary data and JSON respectively.

Anonymize

Detects PII in a PDF and returns a redacted copy of the document. Choose which PII categories to redact (dates, names, emails, addresses, credit cards, and more), or leave the defaults to redact all supported tags.

Anonymize with Custom Prompt

Redacts a PDF using a free-form natural-language instruction instead of a predefined tag list, e.g. "Redact all dates, names, and email addresses".

Detect PII

Scans a PDF for sensitive information and returns the detected entities with location data, without modifying the document.

Supported tags

DATE, PERSON_NAME, ORGANIZATION, LOCATION, EMAIL, PHONE, ID, ACCOUNT, ZIP_CODE, ADDRESS, IP, URL, SSN, DRIVER_LICENSE, PASSPORT, PASSWORD, AGE, CREDIT_CARD, MONEY_AMOUNT, SIGNATURE, QR_CODE, FACE

Both standard digital PDFs and scanned/image-based documents are supported via OCR, across multiple languages.
