API Reference

Core objects

Make sure you go through our core objects documentation to understand the key entities you’ll be working with.

Authentication

This is a key aspect of working with the Dfns API. You’ll need to include a token in the headers of your requests to authenticate to all APIs, but also to sign change-inducing requests. See the API Authorization documentation for more details. We use passkeys to replace passwords, you can read all about it in our credentials documentation.
