# TagResource
<a name="API_TagResource"></a>

Adds or overwrites one or more tags for the specified WorkSpaces Applications resource. You can tag WorkSpaces Applications image builders, images, fleets, and stacks.

Each tag consists of a key and an optional value. If a resource already has a tag with the same key, this operation updates its value.

To list the current tags for your resources, use [ListTagsForResource](API_ListTagsForResource.md). To disassociate tags from your resources, use [UntagResource](API_UntagResource.md).

For more information about tags, see [Tagging Your Resources](https://docs.aws.amazon.com/appstream2/latest/developerguide/tagging-basic.html) in the *Amazon WorkSpaces Applications Administration Guide*.
