API and Integrations

Our comprehensive RESTful XML and JSON API enables full integration of OnApp with third-party applications.

OnApp integrates with popular billing applications like HostBill, Ubersmith and WHMCS, and with PHP applications via a wrapper (integration modules are available from the OnApp website: Downloads).

The API makes integration straightforward for other applications too, including other control panels, CRM, support and billing systems.
