With the GFI KerioControl Administration API, you can programmatically access your GFI KerioControl server, integrate it with third-party solutions and write simple scripts to handle advanced administration tasks.

Connect over HTTPS, send a request in a well-known human-readable format (JSON) and receive a response in the same format.

The administration API provides all actions that are available in the GFI KerioControl administration (our internal GFI KerioControl web administration uses the same API).

As an example, you can list Traffic Rules, add new Rules, edit HTTP Filters, read Logs, setup Bandwidth Management and much more with this sophisticated API.

Out of Scope

The following features are not part of this API:

  • GFI KerioControl StaR Reports

  • GFI KerioControl StaR statistics

  • GFI KerioControl StaR client

  • GFI KerioControl StaR Web Filter

  • Settings or configuration which is not available in the web administration. The only way is to set the appropriate configuration file.
