Developers
The seal goes on as the PDF comes out.
A REST API. Your software sends the document, it comes back sealed with its verification link. We wire it with your team.
Three steps.
- 01Create an API key
From your Deepstamp space. One key per environment.
- 02Send the document
When your software generates it, in your user's name.
- 03Keep the sealed PDF
It goes to the client with its verification link. The content stays identical.
