policyid	String	Policy ID.
url	String	When the value of mode is 0, this parameter has a return value. URL to which the rule applies, excluding a domain name.
prefix	Boolean	Whether a prefix is used for the path. If the protected URL ends with an asterisk (*), a path prefix is used.
mode	Integer	Mode. 0: Standard. 1: Advanced.
status	Integer	Rule status. The value can be 0 or 1. 0: The rule is disabled. 1: The rule is enabled.

You need to configure an attribute variable name in the cookie that can uniquely identify a web visitor based on your website requirements. This field does not support regular expressions. Only complete matches are supported. For example, if a website uses the name field in the cookie to uniquely identify a website visitor, select name. header: Set the user-defined HTTP header you want to protect. You need to configure the HTTP header that can identify web visitors based on your website requirements.

value_list_id	String	Reference table ID. It can be obtained by calling the API Querying the Reference Table List. This parameter is mandatory when the suffix of logic_operation is any or all. The reference table type must be the same as the category type.
index	String	Subfield. When Field Type is set to params, cookie, or header, set this parameter based on the site requirements and this parameter is mandatory.

**Table 6** action
Parameter	Type	Description
category	String	Action type: captcha: Verification code. WAF requires visitors to enter a correct verification code to continue their access to requested page on your website. block: WAF blocks the requests. When tag_type is set to other, the value can only be block. log: WAF logs the event only. dynamic_block: In the previous rate limit period, if the request frequency exceeds the value of Rate Limit Frequency, the request is blocked. In the next rate limit period, if the request frequency exceeds the value of Permit Frequency, the request is still blocked. Note: The dynamic_block protection action can be set only when the advanced protection mode is enabled for the CC protection rule.
detail	detail object	Block page information. When protection action category is set to block or dynamic_block, you need to set the returned block page. If you want to use the default block page, this parameter can be excluded. If you want to use a custom block page, set this parameter.
