Watermark customization

Creating unique PDFs

Sending emails

Tracking emails


UniquePDF helps you share and send your PDFs more securely by adding a watermark. You can use our API to create unique PDFs and send them as you wish. You can test this API by sending the PDF created to your email address, without using any request.

API requests are deduced from your account the same way as a classic usage of our online product. A request corresponds to a single unique PDF generated. For example, if you use our API to create and send a unique PDF to 20 people in a single call, it will be counted as 20 requests for your account.

Depending on your plan, you can customize your watermark, and track your emails to see who already opened and see your PDF.

The API is limited to Pro and Enterprise plans only.
