AWS Control Tower customers can now configure tags for the controls that they have enabled in AWS Control Tower. Customers can add, remove, or list tags for the controls in the AWS Control Tower console or by using the tagging APIs. Tags can help you manage, identify, organize, search for, and filter resources. You can create tags to categorize resources by purpose, owner, environment, or other criteria. AWS Control Tower now supports the following tagging APIs:
TagResource – This API call adds tags to controls enabled in AWS Control Tower.
UntagResource – This API call removes tags from controls enabled in AWS Control Tower.
ListTagsForResource – This API call returns tags for controls enabled in AWS Control Tower.
