**Table 4** Request body parameters
Parameter	Mandatory	Type	Description
certificateid	No	String	HTTPS certificate ID. You can call the ListCertificates API to obtain it. This parameter is not required if the client protocol is HTTP. This parameter is mandatory if the client protocol is HTTPS.
certificatename	No	String	Certificate name. This parameter is not required if the client protocol is HTTP. This parameter is mandatory if the client protocol is HTTPS.

policyid	No	String	ID of the protection policy initially used for the domain name. You can call the ListPolicy API to obtain it.
server	No	Array of PremiumWafServer objects	Origin server settings of the protected domain name. This parameter is mandatory when you create a dedicated WAF instance.
block_page	No	BlockPage object	Alarm page configuration. This parameter is optional. When a user-defined page needs to be configured, all subfields of this parameter are mandatory.
forward_header_map	No	Map<String,String>	Field forwarding configuration. WAF inserts the added fields into the header and forwards the header to the origin server. The key cannot be the same as the native Nginx field. The options of Value are as follows: $time_local $request_id $connection_requests $tenant_id $project_id $remote_addr $remote_port $scheme $request_method $http_host $request_length $ssl_server_name $ssl_protocol $ssl_curves $ssl_session_reused -$origin_uri

Example Requests

The following shows how to add a website domain name to a dedicated WAF instance in a specific project. The project ID is specified by project_id, and the domain name is "www.example.com". The protocol used by a client to access the origin server and the protocol used by WAF to forward requests to the origin server are HTTP. The ID of the VPC where the dedicated engine resides is "cf6dbace-b36a-4d51-ae04-52a3319ae247". The origin server address is ipv4 x.x.x.x. The service port used by WAF to forward client requests to the origin server is 80.
