tagResource method

Future<void> tagResource({ required String keyId, required List<Tag> tags, })

Adds or edits tags on a customer managed CMK.

Each tag consists of a tag key and a tag value, both of which are case-sensitive strings. The tag value can be an empty (null) string.

To add a tag, specify a new tag key and a tag value. To edit a tag, specify an existing tag key and a new tag value.

You can use this operation to tag a customer managed CMK, but you cannot tag an AWS managed CMK, an AWS owned CMK, or an alias.

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

The CMK that you use for this operation must be in a compatible key state. For details, see How Key State Affects Use of a Customer Master Key in the AWS Key Management Service Developer Guide.

Cross-account use: No. You cannot perform this operation on a CMK in a different AWS account.

Required permissions: kms:TagResource (key policy)

May throw KMSInternalException. May throw NotFoundException. May throw InvalidArnException. May throw KMSInvalidStateException. May throw LimitExceededException. May throw TagException.

Parameter keyId : Identifies a customer managed CMK in the account and Region.

Specify the key ID or the Amazon Resource Name (ARN) of the CMK.

For example:

• Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab
• Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

To get the key ID and key ARN for a CMK, use ListKeys or DescribeKey.

Parameter tags : One or more tags.

Each tag consists of a tag key and a tag value. The tag value can be an empty (null) string.

You cannot have more than one tag on a CMK with the same tag key. If you specify an existing tag key with a different tag value, AWS KMS replaces the current tag value with the specified one.
