This guide is intended for hosting service providers that have two or more Plesk servers to manage. Good knowledge of the operating system the provider's Plesk servers operate on is required. This can be either of the following: Linux, FreeBSD or Windows.
The purpose of this guide is to provide comprehensive information on integration of Plesk Expand - the hosting automation software that unites multiple Plesk servers on a single hosting platform - with external systems such as billing, accounting and ordering systems. The guide fully describes the two types of integration: through the Plesk Expand Integration API (when an external system calls in Plesk Expand) and through Plesk Expand events (when Plesk Expand calls in an external system).
