UntagResourceCommand

Deletes tags from a customer managed key . To delete a tag, specify the tag key and the KMS key.

Tagging or untagging a KMS key can allow or deny permission to the KMS key. For details, see ABAC for KMS  in the Key Management Service Developer Guide.

When it succeeds, the UntagResource operation doesn't return any output. Also, if the specified tag key isn't found on the KMS key, it doesn't throw an exception or return a response. To confirm that the operation worked, use the ListResourceTags operation.

For information about using tags in KMS, see Tagging keys . For general information about tags, including the format and syntax, see Tagging Amazon Web Services resources  in the Amazon Web Services General Reference.

The KMS key that you use for this operation must be in a compatible key state. For details, see Key states of KMS keys  in the Key Management Service Developer Guide.

Cross-account use: No. You cannot perform this operation on a KMS key in a different Amazon Web Services account.

Required permissions: kms:UntagResource  (key policy)

Example Syntax

Use a bare-bones client and the command you need to make an API call.

import { KMSClient, UntagResourceCommand } from "@aws-sdk/client-kms"; // ES Modules import
// const { KMSClient, UntagResourceCommand } = require("@aws-sdk/client-kms"); // CommonJS import
const client = new KMSClient(config);
const input = { // UntagResourceRequest
  KeyId: "STRING_VALUE", // required
  TagKeys: [ // TagKeyList // required
    "STRING_VALUE",
  ],
};
const command = new UntagResourceCommand(input);
const response = await client.send(command);
// {};
