# Application Service Templates

Application service templates can be used to instantiate [application services](./service.md) on [devices](../dcim/device.md) and [virtual machines](../virtualization/virtualmachine.md).

!!! note "Changed in NetBox v4.4"

    Previously, application service templates were referred to simply as "service templates". The name has been changed in the UI to better reflect their intended use. There is no change to the name of the model or in any programmatic NetBox APIs.

## Fields

### Name

A service or protocol name.

### Port Mappings

The protocols and ports on which the service runs. See [Port Mappings](./service.md#port-mappings) on the application service model for details.

## Bulk Import (CSV)

Application service templates are imported via CSV using the same `port_mappings` column format as application services. See [Bulk Import (CSV)](./service.md#bulk-import-csv) on the application service model for details.
