Add persistent file protection
to your product.
Without building it yourself.

The PPAD API lets you embed file encryption, access control, revocation, and tracking directly into your platform, so your customers keep control of their files even after they're downloaded.

What you can build with the PPAD API

These are the most common ways teams use PPAD to solve the file control problem inside their own products.

Protect files shared from your portal or cloud storage

Security is attached to the file, so you control it even after it's shared, forwarded, or downloaded, without changing your storage architecture.

Secure paid and subscription content delivery

Protect reports, e-books, training materials, and downloadable assets. Tie access to active subscriptions. Cut off access when they lapse.

Distribute member or certification files at scale

Encrypt and deliver large numbers of protected files through your own app or portal, with per-recipient access controls applied automatically.

Extend protection beyond the data room

Keep fundraising, due diligence, and transaction files protected after they're exported or downloaded from your VDR.

Keep files out of AI tools after delivery

Once a file is downloaded, recipients can copy, screenshot, or upload it to any AI tool. PPAD blocks extraction and keeps files encrypted so that access, and what recipients can do with content, stays under your control.

Automate protection for high-volume workflows

Programmatically encrypt large file libraries on upload, delivery, or distribution, at any scale.

Up and running in four steps

1

Create an API key

Generate an API key to authenticate requests to the PPAD Core API.

2

Protect a file

Use the API to transform a supported file into a secure, encrypted .ppad file with persistent protection attached.

3

Manage recipients and permissions

Control who can access a file and update recipient permissions as needed, before and after delivery.

4

Subscribe to webhooks

Receive real-time event notifications for file and recipient activity directly in your own systems.

Core API concepts

Files

Transform supported files into secure, encrypted .ppad files with persistent protection. Supports PDFs, Word, Excel, images, video, and audio.

Recipients

Add, remove, and update recipient access and permissions on any protected file, at any time after delivery.

Permissions

Control access with rules including watermarking, expiration, copy restrictions, and recipient-specific permissions.

Analytics

Track file activity and access behaviour with detailed analytics: opens, views, time spent, and page-by-page engagement.

Webhooks

Subscribe to file and recipient lifecycle events in real time. Build automated responses into your own systems when file activity changes.

API Keys

Manage authentication for your integration. Scope keys to specific operations and rotate them as needed.

Build actions around file and recipient events

PPAD sends real-time webhook events for file and recipient lifecycle changes, so your product can respond automatically.

If a recipient is removed

  • Revoke access in connected systems
  • Notify admins
  • Update CRM or internal records

If permissions change

  • Sync permissions to your app
  • Log the change for audit review
  • Trigger a compliance workflow

If a file is deleted

  • Update internal records
  • Alert owners or admins
  • Archive the event for audit purposes
