URI

PUT /v1/{project_id}/premium-waf/host/{host_id}

Table 1 Path Parameters

Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID
host_id	Yes	String	ID of the domain name protected by the dedicated WAF engine

Request Parameters

Table 2 Request header parameters

Parameter	Mandatory	Type	Description
Content-Type	Yes	String	Content type. Default value: application/json;charset=utf8 Default: application/json;charset=utf8
