Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID. For details about how to obtain it, see Obtaining a Project ID.
instance_id	Yes	String	Gateway ID, which can be obtained from the gateway information on the APIG console.

**Table 2** Query Parameters
Parameter	Mandatory	Type	Description
offset	No	Long	Offset from which the query starts. If the value is less than 0, it is automatically converted to 0. Default: 0

orchestration_name	No	String	Orchestration rule name.
precise_search	No	String	Parameter name for exact matching. Separate multiple parameter names with commas (,). Only orchestration_name is supported.
orchestration_id	No	String	Orchestration rule ID. Separate multiple orchestration rule IDs with commas (,). The maximum number of IDs is the maximum number of rules that can be bound to an API. For details, see "Quotas" in APIG Service Overview.

Status code: 200

**Table 4** Response body parameters
Parameter	Type	Description
size	Integer	Length of the returned resource list.
total	Long	Number of resources that match the query conditions.
orchestrations	Array of OrchestrationBaseResp objects	Orchestration rules that are queried.

**Table 5** OrchestrationBaseResp
Parameter	Type	Description
orchestration_name	String	Orchestration mapping rule name. The name must be 3 to 64 characters long, start with a letter and use only letters, digits, and underscores (_). It must be unique in the same gateway. Minimum: 3 Maximum: 64
orchestration_strategy	String	Orchestration policy. Options: list hash range hash_range none_value default head_n tail_n. If the orchestration policy is list, the number of objects in orchestration_map multiplied by that in map_param_list cannot exceed 3,000. Enumeration values: list hash range hash_range none_value default head_n tail_n
orchestration_mapped_param	OrchestrationMappedParam object	Parameter configuration after orchestration. This parameter is mandatory when isPreprocessing is set to false.
is_preprocessing	Boolean	Indicates whether the policy is a preprocessing policy. A preprocessing policy generates only temporary parameters as the input of the subsequent parameter orchestration rule. And it cannot be used as the last orchestration rule except the default orchestration rule.
orchestration_id	String	Orchestration rule ID.
orchestration_create_time	String	Time when an orchestration rule was created.
orchestration_update_time	String	Time when an orchestration rule was updated.

**Table 6** OrchestrationMappedParam
Parameter	Type	Description
mapped_param_name	String	Name of the request parameter after orchestration. The value can contain 1 to 128 characters, including letters, digits, and hyphens (-). It must start with a letter and cannot be the same as an existing parameter name. By default, the parameter name is transparently transmitted to the backend. Minimum: 1 Maximum: 128
mapped_param_type	String	Type of the parameter after orchestration. The value can be string or number. Enumeration values: string number
mapped_param_location	String	Position of the orchestrated parameter. The value can be query or header. Enumeration values: query header

Status code: 400
