Calling Method

For details, see Calling APIs.

URI

POST /v1/{project_id}/{resource_type}/resource_instances/action

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID. Minimum: 1 Maximum: 64
resource_type	Yes	String	Specifies the resource type. The type is endpoint_service or endpoint.

Request Parameters

**Table 2** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	Specifies the user token. It can be obtained by calling the IAM API. The value of X-Subject-Token in the response header is the user token.
Content-Type	No	String	Specifies the MIME type of the request body. Default value application/json is recommended. For APIs used to upload objects or images, the MIME type varies depending on the flow type. Default: application/json

**Table 3** Request body parameters
Parameter	Mandatory	Type	Description
tags	No	Array of TagValuesList objects	Tags are included. A maximum of 10 tag keys are included, and each tag value can have a maximum of 10 values. Each tag value can be an empty array, but the tag structure cannot be missing. Tag keys must be unique. Values of the same tag key must be unique. Specifies all returned tags of the resource. Keys are in the AND relationship while values in the key-value structure are in the OR relationship. If no filtering condition for tags is specified, full data is returned. Array Length: 1 - 10
tags_any	No	Array of TagValuesList objects	Any tags are included. A maximum of 10 tag keys are included, and each tag key can have a maximum of 10 values. Values of each tag key can be an empty array, but the tag structure cannot be missing. Both tag keys and values of the same tag key must be unique. Specifies resources including tags returned. Keys and values in the key-value structure are in the OR relationship. If no filtering condition is specified, full data is returned. Array Length: 1 - 10
not_tags	No	Array of TagValuesList objects	Tags are excluded, a maximum of 10 tag keys are included, and each tag value can have a maximum of 10 values. Each tag value can be an empty array, but the tag structure cannot be missing. Tag keys must be unique. Values of the same tag key must be unique. Specifies resources excluding tags returned. Keys are in the AND relationship while values in the key-value structure are in the OR relationship. If no filtering condition is specified, full data is returned. Array Length: 1 - 10
not_tags_any	No	Array of TagValuesList objects	Any tags are excluded, a maximum of 10 tag keys are included, and each tag value can have a maximum of 10 values. Each tag value can be an empty array, but the tag structure cannot be missing. Tag keys must be unique. Values of the same tag key must be unique. Specifies resources excluding tags returned. Keys are in the AND relationship while values in the key-value structure are in the OR relationship. If no filtering condition is specified, full data is returned. Array Length: 1 - 10
sys_tags	No	Array of TagValuesList objects	Specifies the system tags.
limit	No	String	Specifies the number of records to be queried. This parameter is unavailable when action is set to count. If action is set to filter, the default value is 1000. The maximum value of limit is 1000 and the minimum value is 1.
offset	No	String	Specifies the index position and offset. The query starts from the data after the first data offset. This parameter is unavailable when action is set to count. If action is set to filter, the default value is 0 which indicates that the query starts from the first data. The value must be a non-negative number.
action	Yes	String	Specifies the action, which only can be filter and count. If this parameter is set to filter, the query is performed based on the filter criteria. If the parameter is set to count, only the total number of resources need to be returned.
matches	No	Array of Match objects	Specifies the search field. The tag key is the field to be matched, for example, resource_name. The tag value indicates the matched value. The tag key is a fixed dictionary value and cannot be a duplicate key or an unsupported key. Specifies whether fuzzy match is required based on the value of the tag key. For example, if the tag key is resource_name, fuzzy search (case-insensitive) is used by default. If value is an empty string, exact match is used. An empty list is returned because the resource_name for most services cannot be left blank. If the tag key is resource_id, exact match is used. Only resource_name for key is supported. Other key values will be available later.
without_any_tag	No	Boolean	The default value is false. The value can be true or false. When withoutAnyTag is set to true, ignore parameter verification on the tags, tagsAny, notTags, and notTagsAny.

**Table 4** TagValuesList
Parameter	Mandatory	Type	Description
key	Yes	String	Specifies the tag key. It contains a maximum of 127 Unicode characters. A tag key cannot be left blank. (The character set of this parameter is not verified during the search.) The tag key cannot be left blank, empty strings, or spaces. Before you verify and use it, delete spaces at the beginning and end of the tag key. Minimum: 1 Maximum: 36
values	Yes	Array of strings	Specifies the tag values. Each tag value contains a maximum of 255 Unicode characters. Before you verify and use it, delete spaces at the beginning and end of the tag value. The tag value can be an empty array but cannot be left blank. If values is left blank, it indicates any_value (querying any value). Values are in the OR relationship. The system does not verify the character set of values when searching for resources, but only verifies the length. Minimum: 1 Maximum: 255 Array Length: 1 - 1000

**Table 5** Match
Parameter	Mandatory	Type	Description
key	Yes	String	Indicates the tag key. Only resource_name for key is supported. Other key values will be available later. Minimum: 1 Maximum: 36
value	Yes	String	Value. Each value can contain a maximum of 255 Unicode characters. The character set of value is not verified. Minimum: 1 Maximum: 43

Response Parameters
