Developing for Citrix Hypervisor

Explore SDKs and Tools

SDK Overview

Citrix Hypervisor can be programatically managed using the XenAPI or XAPI. XAPI is an open source sub-project of the Xen Project. XAPI is an XML-RPC based API, providing programmatic access to the extensive set of Citrix Hypervisor management features. The Citrix Hypervisor API can be called from a remote system as well as local to the Citrix Hypervisor host. Remote calls are generally made securely over HTTPS, using port 443.

There are five SDKs available, one for each of C, C#, Java, PowerShell, and Python. Prior to Citrix Hypervisor 6.1, these SDKs were available under a LGPL/GPL license model, but the current SDKs use a BSD license. All SDKs are backwards compatible to Citrix Hypervisor 4.0, but it is always preferable to use the most recent SDK. To ensure a graceful fallback, client programs are expected to call host.software_version["product_version"] when appropriate.
