Batch Adding or Deleting Tags to or from a Public NAT Gateway

Function

This API is used to batch add or delete tags to or from a public NAT gateway.

Tag Management Service (TMS) needs to use this API to manage tags of resources in batches.

A resource can have up to 20 tags.

Constraints

  • This API is idempotent.

    • If there are duplicate keys in the request body when you add tags, an error is reported.

    • If a tag to be added has the same key as an existing tag, the tag will be added and overwrite the existing one.

    • During tag deletion, if some tags to be deleted do not exist, the operation is considered to be successful by default. The character set of the tags will not be verified. A key can contain up to 128 Unicode characters, and a value can contain up to 255 Unicode characters. In addition, the tags structure cannot be missing, and key cannot be left blank or be an empty string.

Calling Method

For details, see Calling APIs.

Authorization Information

Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions.

  • If you are using role/policy-based authorization, see Permissions Policies and Supported Actions for details on the required permissions.
  • If you are using identity policy-based authorization, the following identity policy-based permissions are required.

Table 1 Path Parameters

Parameter

Mandatory

Type

Description

project_id

Yes

String

Specifies the project ID.

nat_gateway_id

Yes

String

Specifies the public NAT gateway ID.

Request Parameters

Table 2 Request header parameters

Parameter

Mandatory

Type

Description

X-Auth-Token

Yes

String

Specifies the user token.

It is a response to the API for obtaining a user token. This API is the only one that does not require authentication.

The value of X-Subject-Token in the response header is the token value.
Table 3 Request body parameters

Parameter

Mandatory

Type

Description

tags

Yes

Array of PublicTags objects

Specifies the tag list. For details, see the Tags field description.

action

Yes

String

Specifies the operation to perform. The value can be:

  • create

  • delete
Table 4 PublicTags

Parameter

Mandatory

Type

Description

key

Yes

String

Specifies the tag key. A key can contain up to 128 Unicode characters. key cannot be left blank. A key cannot contain ASCII characters (0–31 decimal) nor the following characters: = * < > \ , | /

value

Yes

String

Specifies the value. Each value can contain up to 255 Unicode characters. If value is specified, tags are deleted by key and value. If value is not specified, tags are deleted by key. value can be an empty string. A value cannot contain ASCII characters (0–31) nor the following characters: =*<>,|/

Response Parameters

Status code: 204

Tags added or deleted.

None
