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 and support and billing systems.
For more detail on the OnApp API, refer to the API Guide.
