### Parameters

`(object/array)` Host properties to be updated.

The `hostid` property must be defined for each host, all other
properties are optional. Only the given properties will be updated, all
others will remain unchanged.

Note, however, that updating the host technical name will also update
the host's visible name (if not given or empty) by the host's technical
name value.

Additionally to the [standard host properties](object#host), the method
accepts the following parameters.

|Parameter|[Type](/manual/api/reference_commentary#data_types)|Description|
|--|--|------|
|groups|object/array|Host [groups](/manual/api/reference/hostgroup/object#host_group) to replace the current host groups the host belongs to.<br><br>The host groups must have the `groupid` property defined. All host groups that are not listed in the request will be unlinked.|
|interfaces|object/array|Host [interfaces](/manual/api/reference/hostinterface/object) to replace the current host interfaces.<br><br>All interfaces that are not listed in the request will be removed.|
|tags|object/array|Host [tags](/manual/api/reference/host/object#host_tag) to replace the current host tags.<br><br>All tags that are not listed in the request will be removed.|
|inventory|object|Host [inventory](/manual/api/reference/host/object#host_inventory) properties.|
|macros|object/array|[User macros](/manual/api/reference/usermacro/object) to replace the current user macros.<br><br>All macros that are not listed in the request will be removed.|
|templates|object/array|[Templates](/manual/api/reference/template/object) to replace the currently linked templates. All templates that are not listed in the request will be only unlinked.<br><br>The templates must have the `templateid` property defined.|
|templates\_clear|object/array|[Templates](/manual/api/reference/template/object) to unlink and clear from the host.<br><br>The templates must have the `templateid` property defined.|

::: notetip
As opposed to the Zabbix frontend, when `name` (visible
host name) is the same as `host` (technical host name), updating `host`
via API will not automatically update `name`. Both properties need to be
updated explicitly.
