Today, we made available the new Resource Groups Tagging API, which makes it easier for you to use tags to centrally organize, discover, allocate costs, and control access to AWS resources. The API’s five operations enable you to programmatically tag and untag resources, list resources with a specific tag, and list unique tag keys across multiple AWS services. With this new API, you can now programmatically use AWS resource group and Tag Editor functionality. This makes it easier for you to implement automated tools to manage, search, and filter tags and resources across AWS services.
