Table 1 Path Parameters

Parameter

Mandatory

Type

Description

project_id

Yes

String

Specifies the project ID.For details about how to obtain the project ID, see Obtaining the Project ID.

resource_type

Yes

String

Specifies the resource type. Possible values are:

smn_topic: topic

smn_sms: SMS

smn_application: mobile push

Request Parameters

Table 2 Request header parameters

Parameter

Mandatory

Type

Description

X-Auth-Token

Yes

String

Specifies a user token.

It can be obtained by calling an IAM API. The value of X-Subject-Token in the response header is the user token.
Table 3 Request body parameters

Parameter

Mandatory

Type

Description

tags

No

Array of ResourceTags objects

A maximum of 10 tag keys are allowed in each query operation. Each tag key can have up to 10 tag values. The structure body is mandatory. The tag key cannot be left blank or be an empty string. Each tag key and tag values of one key must be unique. Resources identified by different keys are in AND relationship.

tags_any

No

Array of ResourceTags objects

A maximum of 10 tag keys are allowed in each query operation. Each tag key can have up to 10 tag values. The structure body is mandatory. The tag key cannot be left blank or be an empty string. Each tag key and tag values of one key must be unique. Resources identified by different keys are in OR relationship.

not_tags

No

Array of ResourceTags objects

A maximum of 10 tag keys are allowed in each query operation. Each tag key can have up to 10 tag values. The structure body is mandatory. The tag key cannot be left blank or be an empty string. Each tag key and tag values of one key must be unique. Resources identified by different keys are in NAND relationship.

not_tags_any

No

Array of ResourceTags objects

A maximum of 10 tag keys are allowed in each query operation. Each tag key can have up to 10 tag values. The structure body is mandatory. The tag key cannot be left blank or be an empty string. Each tag key and tag values of one key must be unique. Resources identified by different keys are in NOR relationship.

offset

No

String

Specifies the index position. The query starts from the next data record indexed by this parameter. You do not need to specify this parameter when you query resources on the first page. When you query resources on subsequent pages, set this parameter to the location returned in the response body for the previous query.If action is set to count, this parameter does not take effect.If you set action to filter, the offset value is 0 by default. The offset value cannot be a negative integer.

limit

No

String

Specifies the maximum number of resources to be queried.

If action is set to count, this parameter does not take effect.

If you set action to filter, the value of this parameter is 1000 by default. The maximum value of limit is 1000 and the minimum value is 1.

action

Yes

String

Specifies the operation to be performed. The value can be filter (filtering) or count (querying the total number).

filter indicates pagination query. count indicates that the total number of query results meeting the search criteria will be returned.

matches

No

Array of TagMatch objects

Specifies the key-value pair to be matched.

The key can only be resource_name.

The value will be exactly matched.
