Adding a Tag to a Public NAT Gateway

Function

  • This API is used to add a tag to a public NAT gateway. A resource can have up to 10 tags.

Constraints

  • This API is idempotent.

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

  • Ensure that a NAT gateway is available.

Calling Method

For details, see Calling APIs.

URI

POST /v3/{project_id}/nat_gateways/{nat_gateway_id}/tags

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.
