API Reference (API Version 2014-11-01)

TagResource

Adds or overwrites one or more tags for the specified customer master key (CMK). You cannot perform this operation on a CMK in a different AWS account.

Each tag consists of a tag key and a tag value. Tag keys and tag values are both required, but tag values can be empty (null) strings.

You cannot use the same tag key more than once per CMK. For example, consider a CMK with one tag whose tag key is Purpose and tag value is Test. If you send a TagResource request for this CMK with a tag key of Purpose and a tag value of Prod, it does not create a second tag. Instead, the original tag is overwritten with the new tag value.

For information about the rules that apply to tag keys and tag values, see User-Defined Tag Restrictions in the AWS Billing and Cost Management User Guide.
