Response Parameters

Status code: 200

**Table 4** Response body parameters
Parameter	Type	Description
total	Integer	Number of rules in the policy
items	Array of CustomRule objects	Array of rules

**Table 5** CustomRule
Parameter	Type	Description
id	String	Policy ID.
policyid	String	Rule ID.
description	String	Rule description.
status	Integer	Rule status. The value can be 0 or 1. 0: The rule is disabled. 1: The rule is enabled.
conditions	Array of conditions objects	List of matching conditions. All conditions must be met.
action	CustomAction object	Protective action of the precise protection rule.
action_mode	Boolean	This parameter is reserved and can be ignored.
priority	Integer	Priority of a rule. A small value indicates a high priority. If two rules are assigned with the same priority, the rule added earlier has higher priority. Value range: 0 to 1000.
timestamp	Long	Timestamp when the precise protection rule is created.
time	Boolean	Time the precise protection rule takes effect. false: The rule takes effect immediately. true: The effective time is customized.
start	Long	Timestamp (ms) when the precise protection rule takes effect. This parameter is returned only when time is set to true.

producer	Integer	This parameter is reserved and can be ignored.
name	String	Rule name.

**Table 6** conditions
Parameter	Type	Description
category	String	Field type. The options are url, user-agent, ip, params, cookie, referer, header, request_line, method, and request.
index	String	Subfield If the field type is url, user-agent, ip, refer, request_line, method, or request, index is not required. If the field type is params, header, or cookie, and the subfield is customized, the value of index is the customized subfield.
logic_operation	String	Logic for matching the condition. The options are contain, not_contain, equal, not_equal, prefix, not_prefix, suffix, and not_suffix. For more details, see the console UI.
contents	Array of strings	Content of the conditions.
value_list_id	String	Reference table ID.

**Table 7** CustomAction
Parameter	Type	Description
category	String	Protection type block: WAF blocks attacks. pass: WAF allows requests. log: WAF only logs discovered attacks.
followed_action_id	String	ID of a known attack source rule. This parameter can be configured only when category is set to block.

Status code: 400

**Table 8** Response body parameters
Parameter	Type	Description

details	Array of IAM5ErrorDetails objects	The set of error messages reported when a downstream service is invoked. This parameter is returned only when an IAM 5 authentication error occurs.

**Table 9** IAM5ErrorDetails
