**Table 1** Parameter description
Parameter	Mandatory	Type	Description
project_id	Yes	String	Specifies the project ID.
resource_type	Yes	String	Specifies the resource type. An example value is scaling_group_tag.

Request

**Table 2** Request parameters
Parameter	Mandatory	Type	Description
tags	No	Array of Tag objects	Specifies filter criteria with tags included. A maximum of 10 keys can be contained. The structure body must be complete. For details, see Table 3.
tags_any	No	Array of Tag objects	Specifies filter criteria with any tag included. A maximum of 10 keys can be contained. For details, see Table 3.
not_tags	No	Array of Tag objects	Specifies filter criteria without tags included. A maximum of 10 keys can be contained. For details, see Table 3.
not_tags_any	No	Array of Tag objects	Specifies filter criteria without any tag included. A maximum of 10 keys can be contained. For details, see Table 3.
limit	No	String	Specifies the maximum number of query records. The maximum value is 1,000, and the minimum value is 1. If action is set to count, this parameter is invalid. If action is set to filter, the default value is 1000.
marker	No	String	Marks the paging location (index position). You are advised to use the offset parameter to set the index position. Marks the paging location (resource ID or index location).
action	Yes	String	Specifies the operation, which can be filter or count. filter: indicates that resources are filtered by tag and the resources meeting the search criteria are returned on pages. count: indicates that resources are searched by tag and the number of resources meeting the search criteria is returned.
offset	No	String	Specifies the index position. The query starts from the next image indexed by this parameter. The value must be a non-negative number. You do not need to specify this parameter when querying resources on the first page. When you query resources on subsequent pages, set offset to the location returned in the response body for the previous query. If the action value is count, this parameter is invalid. If the action value is filter, the default value is 0.
matches	No	Array of match objects	Specifies fuzzy search. For details, see Table 4.

**Table 3** **Tag** field description
Parameter	Mandatory	Type	Description
key	Yes	String	Specifies the tag key. It contains a maximum of 36 Unicode characters. It cannot be left blank (This parameter is not verified in the search process.) A maximum of 10 keys are allowed and the key cannot be left blank or an empty string. Each key must be unique.
values	Yes	Array of strings	Specifies tag values. A value contains a maximum of 43 Unicode characters. A key contains a maximum of 10 values. Each value of the same key must be unique. The asterisk () is reserved for the system. If the value starts with , it indicates that fuzzy match is performed for the digits following . The value cannot contain only asterisks (). If the values are null (not default), it indicates any_value (querying any value). The resources contain one or multiple values listed in values will be found and displayed.

**Table 4** **match** field description
Parameter	Mandatory	Type	Description
key	Yes	String	Specifies the key based on which to query resources. The parameter value can only be resource_name.
value	Yes	String	Specifies the value. The value is a fixed dictionary value. A value contains a maximum of 255 Unicode characters. If the value is an empty string or resource_id, exact match is used.

Example Request

This example queries the details of AS groups of a tenant using the following search criteria: including the tag (key = key1 and value = value1), excluding the tag (key = key2 and value = value2), index position 100, and a maximum number of 100 records.

POST https: //{Endpoint}/autoscaling-api/v1/{project_id}/scaling_group_tag/resource_instances/action

{
	"offset": "100",
	"limit": "100",
	"action": "filter",
	"matches": [{
		"key": "resource_name",
		"value": "resource1"
	}],
	"not_tags": [{
		"key": "key2",
		"values": ["value2"]
	}],
	"tags": [{
		"key": "key1",
		"values": ["value1"]
	}]
}

This example counts the number of AS groups for a tenant using the following search criteria: including the tag (key = key1 and value = value1) and excluding the tag (key = key2 and value = value2).

POST https: //{Endpoint}/autoscaling-api/v1/{project_id}/scaling_group_tag/resource_instances/action
