Exivity provides a full REST-API which acts as a programmatic interface to each operation supported through the Graphical User Interface (GUI). On top of that, some operations can be exclusively executed through the API (such as file uploads).
A reference guide on all API endpoints and further details about implementation and authentication is publicly available online.
With Exivity it's possible to connect your existing AD/ADFS/AAD user directory so your end-users can benefit from an easy SSO experience.
Currently, Exivity supports the Security Assertion Markup Language (SAML) v2 protocol, supported by i.e. Microsoft ADFS.
We're currently in the planning stages of developing Exivity SDKs in various languages which would make interfacing with the REST-API very straight-forward and easy to implement.
