You can use several interfaces to integrate Horizon 7 with external applications.

Event database
You can configure Horizon 7 to record events to a Microsoft SQL Server or Oracle database. You can then use business intelligence reporting engines to access and analyze this database.
Lightweight Directory Access Protocol (LDAP)
You can export and import LDAP configuration data from and into Horizon 7. You can create scripts that update this configuration data without accessing Horizon Administrator directly.
Windows Management Instrumentation (WMI)
You can examine performance statistics for a PCoIP session.
